ADC 26 BEST PRITCHARD CARTRIDGE EVER? or BEST CARTRIDGE EVER?


Dear friends: I always said that each day is a learning day and if like me that from several years now think always " out of the box " many of you will find out great rewards that audio always has for us as an unexpected gifts.

Obviously that’s not easy to think " out of the box " because to do that we have to have a different kind of self attitude where between other things we must to forget for ever at least the 50% of all the information we learned through our audio life in the AHEE. With out that " forget " we just can’t do it.

This review is more than an usual audio item review for many reasons I will try to explain over the thread.

First I want to leave very clear my room/audio system main target: STAY TRUER TO THE RECORDING.

To achieve that we have to think that usually the recording microphones are positioned at very near field of the MUSIC sources even like in the 3 Blind Mice recordings: inside the instruments. Recording microphones are not " seated " at 20m-35m. from the source as usually we listen when attend to a live acoustical music event. So we have to have self experiences of live MUSIC seated at near field. If some of us do not have that kind experiences then is very dificult to understand what I’m talking about here and elsewhere.

OK, the ADC 26 cartridge is a vintage Induced Magnet invented motor design by Peter Pritchard ( that pass away. ), it’s not a MM or MI or MC kind of cartridge design. Here you can read about and on his patent and a little of his audio life history:


https://www.stereophile.com/content/peter-pritchard

The cartridge under review is this:

http://i41.tinypic.com/2ihw6yo.jpg

that is part of the ADC 25, 26 and 27 cartridge family.

This is the ADC 25:

https://www.vinylengine.com/turntable_forum/download/file.php?id=31979

and this the ADC 27:

https://adelcom.net/ADC-adc%2027.JPG

and here the ADC 26 specs ( please take note those 15° stylus tip mounted angle. ):

https://www.vinylengine.com/library/adc/26.shtml


As you can see and read all seems very old and rudimentary with really humble cartridge specs ( nothing spectacular down there. ) where the elliptical stylus is: 0.03 x 0.07.

The ADC 25 red dot stylus ( exist the red blue 0.03 x 0.09 and the white dot. ) is similar to the 26 and the ADC 27 change is that is the same 26 stylus type but nude. I own all those models that comes with the same cartridge body but different color and where the cartridge motor in the 26 and 27 is similar and the cartridge differs only in the stylus and that the compliance instead 50 cu as in the 25 and 26 is " only " 40cu.

All these cartridges are my oldest ones ( comes from the 60’s. ) that I bougth years ago when started the very long MM Agon thread and I remember that I mentioned there the 25 and 26 but almost no one took cares about not even me because I really never gave it the enougth listening time to those cartridges and was only like a month ago that I really discovery this fenomenal, outstanding, astonishing and " perfect " performer.

When you listen it you are not listen as if was alike MM/MI/electrect cartridges but more as a live event/truer to the recording with some characteristics only shared for the best of the best LOMC cartridges.

I made my self developed evaluation proccess where I’m deep trained and is almost " bullet proof ".

The best MM/MI cartridge is with out doubt the AKG P100LE followed by Astatic MF-2500 and others as the JVC X1MK2 or the Technics EPC 100CMK4 but no one of them can even the quality performance levels of the ADC 26. The ADC is in a different league " the major league ".

I compared the 26/27 against the Colibri, Ortofon A95, Lyra Etna, My Sonic Labs Supereminent ( I think ? ? ) Dynavector XV-1s, Clearaudio Goldfinger and some other vintage top MC designs. No one of them beats overall the ADC 26.

The main 26 characteristics to beat belongs at both frequency extremes where if we want first rate quality performance there first condition is the transient response/attack of the music notes and develops of harmonics along the decay timing that’s where exist clear differences in between MC cartridges and all the other kind of designs. Nothing but the 26/27 compares with a top LOMC cartridges in those regards.

The transient response and fast timing decay in the low of the bass range is second to none and " mimic " what we can listen in a live event at nearfield position. With out this " sole " characteristic MUSIC as MUSIC just can’t exist and is here where belongs the MUSIC foundation.
At the other frequency extreme things are more of the bass range quality performance. In both frequency range it’s not only the rigthness of the transient response but the notes definition its very clear distinction in between and its harmonics. Exist no overhang or bold sound. At the high frequency range ( at the top. ) nothing can beats a Colibri 0.22mv output and the only contender for is precesily these ADC 26/27 ! !

As you can see the 26/27 specs says not very wide frequency range but when listen to it you can sware it goes from 5hz to over 100khz but the more important issue is the clear definition. When the timing in those frequency ranges are spot on then the overall MUSIC rythm is just spectacular and makes and moves all your feelings and body.

We all hear through all our body not only through our ears. We hear through the skin, bones, skind hair and millions of nervous terminations in the body and when you are listening to the ADC 26/27 all those have a true meaning as never before.

What about soundstage, layering, inner detail and the like: just very first rate. Tonal balance is outstanding nothing at the broad wide frequency range tells you " hey: I’m here ", exist a true coherence in between all frequency ranges.

Yes, it’s a UNIQUE listen experience a NEW listen experience coming from a very older cartridge and YES is the best Pritchard design and if you think that you already own the best cartridge ever you need to experience the ADC 26/27. I compared against the best out there in the same system with the same tonearms and same everything.

Was not only me but some other audiophiles friends where at least one of them is a music player. This one is a drummer/batery player and when he was at my place I run ( between other LPs. ) the Sheffield D2D with Ron Tutt and Jim Keltner great drummers with out telling him which cartridge was playing and my friend that’s a true expert with those instruments and golden ear by nature was " jaws dropping " and it’s because is incredible the TRUE of that kind of sound coming from the ADC’s
. This recording specially is something to listen through the 26/27 at 95db SPL with peaks in the 100db neigborhood, you can touch the sound and cut it with a sizzers ! ! !. It’s amazing.
The ADC never lost its aplomb no matters at what SPL you are listening from 70db to over 95dbs .

Every single good recording " sings " as never before of all what I experienced in my system and several other top audio systems.

One of the best MUSIC LP for testing any audio item is the Telarc 1812 and not because the cannon shots but overall frequency ranges that’s always a challenge for any cartridge andd for any audio system in other frequency ranges than the bass range.
No one of the other top LOMC cartridges can even overall the ADC 26/27 quality performance levels in this LP recording in all the frequency range other than the very low bass where the ADC beats to all of them.

I running the ADC 26 at 1.1grs and due ot its very high compliance ( 50cu. ) and cartridge body design is a very low rider when the 27 is only a low rider.
As with other top LOMC cartridges the alignment set up is critical but with the ADC 26 we have to do it with the best accuracy we can and with the VTA/SRA tiny/sligthly up at the tonearm bearing. This VTA/SRA is critical and as always not only depends of the accuracy overall set up but room system dependent.

That explosiveness, power, dynamics, transient response, thightness, flow, true tonal balance agresiveness, natural brigthness, rythm that usually exist only in a live MUSIC event with the ADC 26/27 you can feel that never was in your home audio system as nearer as with these ADC cartridges.

Those audiophiles terms as: lush, organic, color, smothness, bold, and the like does not exist through these " truer to the recording " performers. Those audiophiles terms/characteristics of sound just does not exist in the nearfield MUSIC live events are only characteristics " invented by the AHEE and very far away from reality.

The ADC 26/27 as the very top LOMC cartridges are made it for true music lovers more than for " audiophiles ".

I think that in the 60’s the ADC 26/27 you can get fro no more than 80.00 and today can compete against 15K+ LOMC cartridges.

This all new experience through the ADC 26/27 bcartridges came in the best moment when I 'm more mature in all subjects with MUSIC and audio and when my room audio system is at its best with all the up-dates and up-grades I can afford bor the better.

As always your contributions in the thread all are welcomed and appreciated.


Regards and enjoy the MUSIC NOT DISTORTIONS,

Dear @lewm : ADC were made it in USA as Sonus second Pritchard company too. The 26/27 outperforms " face to face " with all the same system to any Sonus models.

Yes, you are rigth that I own more than one ADC 26 cartridge motor and original stylus and I owned for so many years that I not even remember of those great ADC models till I found out by " accident " looking for other cartridge in my closet.

But here I posted to adc-grace ( I think ? ? ) that what I will do is what he said in his last post: to re-tip one of my stylus replacement for the best today stylus shape as could be Micro Ridge or something like that and I'm totally sure that as impressive as is the stock ADC 26/27 quality performance high levels it will be a " little " more impressive. 
Btw, the 26 and 27 stylus are the same but the 27 is nude version of the 26 stylus .

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
Dear @adc-grace : TRX motor is same principle and performs very well. I owned the TR2 and still own the TRX 1 because the ! like me more than the 2.

Agree with you the ADC 25/26/27 is better quality performer and superior to the JVC and any Signet cartridge.

R.
By the way, I have not owned an XLM since the early 1970s. I found it to be lacking. But it was all the rage for a year or two back then.
Chakster, but who are you to declare what is the value of this or that cartridge or tonearm? No one single person can do that. Your opinion is just one of many and has no more stature than anyone else’s with any expertise. In fact I can recall one instance when it appeared superficially that you raved about a certain cartridge or tonearm and then went on to be a seller. No need to rehash that here.  I have no problem with that. As I said.

 Raul has gone through several dozens of cartridges in his search for Nirvana. I think he does have two or 3 ADC 26s. So what’s the problem if he sells one? The value will be in the eye of the buyer. Evidently  Raul is asking too much for the market to bear right now. And ultimately the market will determine  what his cartridge it is worth. By the way, I will buy all the ADC 26s that you can find me for $200 each. Provided they are in mint or NOS condition.
@lewm maybe you missed his post in another thread where he said he's taking serious offers on his "best ever" ADC, link to this "review" has been provided. I have nothing to add about his methodology of product placement. 

I can't remember i have ever started a thread or review just to sell any of my spares. Can't remember that someone like Nandric did the same or anyone else, did you? We can recommend nice carts when people ask for it. I can't say which cart "is the best ever." Each Raul's cart is the best ever in his opinion, but in his own world only. 

In my opinion if any cartridge cost a lot there is a reason for it, first reason in material used (cantilever, diamond profile, coil wire etc, cartridge body etc) and overall condition, rarity and market demand for it. There is also price statistics available for everyone. 

The ADC 26 is $200 cartridge with cheap body, average stylus and cantilever. Designed in the 60's before your XLM, long before my TRX-2, before any Sonus. The 60's isn't the best time for hi-fi cartridges, but the OP claimed it was the best Pritchard's design, so Pritchard has not been able even to upgrade his carts in the 70's, even with his Sonus brand after ADC? You are free to believe. 
 I don’t know for sure where ADC cartridges were manufactured, but I do recall back in the 70s that the ADC XLM and itS progenitors were much much cheaper in the US than in Europe. In fact at one point when I had to go to London for a scientific conference I brought ten ADC XLM cartridges with me and sold them to a dealer in London for a nice profit.  Presumably he went on to resell them for an additional nice profit to his retail customers. So if the model 26 and its related cartridges was expensive in Europe back in the 60s, maybe it was much cheaper in the US. I have no recollection of that model from the old days. The first ADC cartridge that I knew about was the XLM series.

 Chakster , let’s be fair. Haven’t you also touted cartridges on this forum that you later went on to sell at high prices, largely supported by your own online endorsement? It’s perfectly OK with me for you to do that, but I’m just saying.I think Raul has more than one ADC 26, and perhaps feels he doesn’t need more than one. 
@nandric 

The price for ADC 26 was 22 000 YEN in Japan in the 70's:
https://audio-heritage.jp/ADC/etc/adc-26.html

and it's about the same as not even the best Victor X-1IIe 23 000 YEN at that time:
https://audio-heritage.jp/VICTOR/etc/x-1iie.html

But Victor X-1IIe has titanium cantilever and it's MM type with much better frequency response and "normal" compliance for any tonearm, price for Victor X-1IIe (for example) today is about $300-500 (used) and we have long statistics (sales history).

At the same time the TRX-2 is widely popular with its exotic cantilevers and Vital Diamond Profile and today price is $300-700 max (depends on condition).

So what's the reason for a 60's design of the cartridge with Aluminum cantilever and Elliptical tip to be more expensive than very popular models with exotic materials (the TRX designed by Nakatsuka San, now ZYX) ?

There is no demand for ADC 26 and people who sold that cartridge normally asked very low price for it, because nobody needs it. Even in Netherlands (especially for you my friend), the cost is 175 euro nowadays, look here: https://www.marktplaats.nl/a/audio-tv-en-foto/platenspelers-en-pick-ups/m1375530213-orgineel-adc-26-stereo-element.html

Of course, like our Maxican, enyone could ask crazy price for any cartridge and even create a special thread to sell it for astronomic price with promising title "the best ever?", but normally some smart buyers will look at the price statistic first. If there is no demand for a cartridge the price will never be as high as you suggested. The ADC 26 and related models in this series is extremely cheap in Tokyo, i've seen auction results and this is the reason i said it's a $100 cartridge today, well maybe NOS in the box could be $200-300. In the USA they must be even cheaper.

So as i said, not bad for $100 cartridge.  
@nandric 

The ADC is only the complete Kit. Means ADC cart and 3 differnet Styli.
2 elliptical and on conical.
The ADC 26 or 27 are the versions with only one styli.
I don´t know the JVC and the TK7, but with the TRX it will be on par.
Buit the sound is different more relaxed and natural.

As you say it was no cheap cartridge not in the 60s, not in the 70s or 80s. It was not the peak priced one but quite expensive for this time.

I am sure, the ADC 25 would profit from a "modern" diamond shape like MicroRidge, lineContact or similar on a light sapphire cantilever.
To my experience the most important thing is a really light tonearm. (works even on SL1210, but it is a compromise).

At the moment I choose between the Grace F9 with diff. styli and ADC 25. Depends a little bit on the kind of music and quality of the Vinyl pressing.

As Raul says "Enjoy the music"

M.

@adc-grace, I am 100% sure about my first ADC 25. In the

70is it was one of the most expensive carts. To be precise 250

Dutch Gulden (= DM). So chakster ''estimation'' or qualification

as ''cheap cart'' is not correct. My scholarship back then was 200

Gulden.  So considering inflation the cart should be above

1000 euro at present. Alas I forget how ADC 25 sounded but

my ADC 26 is anyway equal to TRX, II Berillium, JVC X-1,mk2

and AT TK 7 CL.

@nandric 
I have tried my TRX. It is a TRX 2 with TRX 1 stylus. Bought it like it is.

It is a very good performer. Nice sound, good stage, very wide but not extremly deep. Good highs and bass. Very good card.

Compered to the ADC 25 it is also nice but not that "flowing".
In my system the ADC 25 is very natural. Voices sound incredible, nearly like real. The 25 is more balanced and natural. The highs are not that bright, but also good. Bass is deep and tight and the mids are very natural too.

This is only a first and fast opinion.

Cheers

Dear chakster, ''Welcome back?'' If you mean to the ''old MM

thread time'' yes. The time when we earned money with our carts

obsession provided we were very vast and, of course, thanks

to Raul. That is btw why I still own 40 of those kinds.

I discovered by accidence the ADC 26 in one of my (many) ''parts

boxes''. I directly imagined , say, $1000 price. But your practical

logic is to praise the AT 170/180 of which you own an whole

collection and criticize ADC 26 for obvious reasons.

Well as is usual among brothers you get my advice for free.

When you sell all your AT's you my ''accumulate'' sufficient

capital to buy Ikeda 9 REX. The real ''best ever cart'' of all

kinds (grin).

I’m glad you’re back @nandric

Look, accoring to the spanish speaking in this thread:

The best MM/MI cartridge is with out doubt the AKG P100LE followed by Astatic MF-2500 and others as the JVC X1MK2 or the Technics EPC 100CMK4 but no one of them can even the quality performance levels of the ADC 26. The ADC is in a different league " the major league ".

I compared the 26/27 against the Colibri, Ortofon A95, Lyra Etna, My Sonic Labs Supereminent ( I think ? ? ) Dynavector XV-1s, Clearaudio Goldfinger and some other vintage top MC designs. No one of them beats overall the ADC 26.

and for this reason he decided to sell his "ADC 26 BEST CARTRIDGE EVER? " (he wrote it with caps-lock as usual). Can you imagine? I saw his post where he's selling that "best ever" ADC

How would you comment the logic behind this decision ? Just curious :)

I would beliebe more if your statement about ADC and your 40 MM and a dosen on LOMC cartridges will be the same.

Also i think you would play all the record only with ADC 26 (not with Ikeda) if the quality of this cartridge is so high compared to others.

Right ?





@chakster , Curious sense for humor or teasing. I can also

imagine something or other but not why whomever would be

interested in the last time I listened to some of my (40) MM

kinds? From my ''confession'' that I prefer MC kinds one can't

deduce that I don't listen to MM kinds. There is something wrong

with your logic. The reason is that Russian believe in Hegel's

logic. He wrote two books about logic with more than 1000 pages

but there is no one single sentence relevant for modern logic

since Frege. 

@adc-grace

What only one day in high school?!?

He could stay with "MM/MI sound" for one day or one night only, haha

... and then to mount his cantilever-less Ikeda LOMC cartridge back for full enjoyment. 

p.s. i also like cartridges designed by Ikeda. 





@nandric so you like ADC 26 too ? I'm surprised, because i can imagine when the last time you have ever used MM or MI cartidge, i think that was the days then i was in high school :)  

Dear chakster, ''the best ever'' is a way of speaking. Like

metaphors. One woud need to know how all cartridges ever

produced sounds in order to make such statement. What we

and you do is rather this: ''from all carts that I own I like ''x'' the

best.

I own TRX 2 in both versions; with sapphire and beryllium cantilever.

The later is slightly better. I also own JVC X-1,mk2, then AT TK

7 CL and ADC 26. All those 4 are my best MM carts.

@chakster 
I only have a TRX 1.
Bought it 2 years ago. But did only a short test for function. It is a little bit different.
Was not bad at all but not the right tonearm.
Will be the next system I will try on my ADC LMF-2 arm (nothing sophisticated, but light and good with different high compilance cartridges).
Perhaps I have time this evening. But I will report to you about it.

Regards
@adc-grace
Forgive me if i asked before, but i'm curious, have you tried the ADC TRX-2 (Sapphire Cantilever / Vital Diamond) in comparison to your different ADC models ?  
Dear Raul,

you are right. You always have to test and test and test.........

With really good cartridges every small change effects the sound. It will sound different in every system, turntable, tonearm, phono-pre etc.

But once you have found good setups it is much easier with other cartridges. You get experience which changed could have a positive effect. The more experience you have the easier and faster you will get good effects.

But the detail is it. Even if I look at my Grace f-9 systems (have 2 original and 2 retiped styli) everyone is different. Different tonearm etc.

But everybody who one a light mass tonearm which is none unipivot (I did not the best experiences) should try an ADC 25/26/27

Regards
M.

Dear @adc-grace : Mi take and next move with one of my ADC samples is like you, I will change cantilever/stylus for boron/ Line contact or Shibata one.

The ADC 25/26/27 cartridge motor is just unique and Pritchard induced magnet design is way superior to MM designs.
There are some really good MM cartridge performers but induced magnet/moving iron/moving flux ( that's a moving iron " refined ". ) as those ADC or Empire 4000D3 and some others that makes a little better " job ".

Obviously that the room/audio system quality level performance has " to much to say " because synergy could change system to system starting with the tonearm where cartridges are seated.

Analog never is " to easy " and with fixed rules.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
@chakster 
Thank you very much.

You are right, I love ADC and Grace, but sadly I didn´t get hold of the F-14 and Level II yet.
The AsaKura´s One I didn´t know yet. But it is an MC. I like MM/MI more due to their more fluid sound. Like from one piece.

Back to the ADC25/26
My next step will be to get a better stylus in the stylus holder. Something like LineContact or MicroRidge. Really interested how the sound will change.

Dear chakster, I don't believe that you can deduce your

statements about ''best carts'' from my statement about

''moving mass''. Moving mass is a part of the total cart

construction but an very important part. The fact that each

designer try to reduce this mass is obvious (?) prove

for this assumption. I am not familiar with other carts you

mentioned but well with FR-fz and AT-180. I think that

you confused ''moving mass'' by FR-7fz with its damper

which is ''responsible'' for the compliance. Besides ''rubber

damping'' is not part of the moving parts . The output by

FR-7fz is ''only'' 0,2 mV and means   little wire for the

 coils which means reduction of mass.

In your opinion the AT 180 is the ''best there is'' but this is

not the case by other opinions. As you know I prefer MC

kinds above any MM kind. So, in some sense, my opinion

about MM kinds is not relevant for ''MM lovers''.

@nandric 

The mass of moving parts is obviously important because all cart producers try to reduce this mass .Lighter cantilever, micro ridge styli  and low uitput coils with as little wire as possible are examples. This is actually the reason for the preference for low-output MC cartridges. However MI cartridges have the lowest moving mass of all cart kinds.


Then why my Grado Signature XTZ (MI) is not the "best cartridge in the world" ? 


Why FR-7fz is so good being huge, superheavy low compliance monster ? 


And why some MM cartridges like Grace F14 and LEVEL-II or AT-ML180 are so good? 


Audiogon these days is like fake news sometimes.

@adc-grace we need your clarification, because Grace deserve respect, do you own the original Grace F14 or LEVEL-2 models or you are comparing your $100-200 ADC 26 to F-9 with the stylus from F-14?

The $400 F-9 is nowere near the $1400 F-14 cartridge.

Which exact model F-14 stylus do you have on your F-9 cartridge?

P.S. the OP is trying to sell his ADC 26 in another thread, so this is just the advertising with caps lock in title? I just don't get it. 
Dear @adc-grace : Good that you own those Grace ones and good that even that are very good does not beats the ADC.

"" 

your adc 26 thread.
All I am able to say is:
You are right!!!!

This is a very outstanding cartridge!!  "


thank's for that.


R.

The mass of moving parts is obviously important because all

cart producers try to reduce this mass .Lighter cantilever, micro

ridge styli  and low uitput coils with as little wire as possible are

examples. This is actually the reason for the preference for low-

output MC cartridges. However MI cartridges have the lowest

moving mass of all cart kinds. One need only to look at B&O and

ADC carts to see this with his own eye. No measurement of any

kind I needed. So it is not wonder that Raul next to ADC 25

kinds also praise B&O kinds. I would add the Austrian AKG kinds

which were excellent,  but alas, used the wrong material  for the

suspension and needed to close cart production to avoid liability.

So the question moved to the ''motor'' , whatever this may mean,

instead to clear the issue of mass.

I know that holistic conception of carts is importnat but there

are those  ''damned  details '' about parts in each holistic approach.


  

@adc-grace welcome on board

Looking at your nickname i thought you’re specializing in Grace and ADC :) You’re right, the F14 and LEVEL II are the rarest Grace MM cartridges. The Asakura’s ONE is the rarest Grace LOMC (amazing cartridge).
@chakster I know the LevelII and the f-14 but they are not easy to get in Europe.

Dear @adc-grace2 : Obviously that I agree with you on the ADC 26/27 cartridge that again as you posted: GREAT PERFORMER, no matters what.

As yours  and other gentlemans  the  @luckyx02 are great contributions with first hand experiences/information that enhance the vision that other audiophiles can have on this cartridge review/thread.

Thank's for that, the ADC is really in a major league and is unfortunated tha Pritchard  pass away.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.


Dear @peetrob : Godd that you like the ADC26. I own your Sonun cartridge model and the top Sonus one, very good performers too.

Your system including the tonearm is different that mine and all what you can read in my review reffered to the ADC26 with 27 nude same shape stylus but even the ADC26 ( stock stylus. ) outperforms with extremely easy facility to its Sonus brothers and to that VDH cartridge.

Please try to read again the review. Anyway, I did it because for me the ADC26/27 is just unbeatable my any other vintage today MM/MI cartridge and as I said in the review is the only very humble ( true humble. ) vintage cartridge that can " talks " with the Etna or Colibri " face to face " with out nothing to " feels " on shame.

Great challenge for every one cartridge.

R.
Even an Grace F-9 with F-14 MicroRidge stylus (much better than any F-9 original stylus) sounds different but not better.

Because the F-9 signal generator is an old generation of Grace compared to the the High-End F-12 and F-14, you have to use your RS14 stylus on F-14 LC-OFC generator if you really want to hear the best from Grace. Those are designed in the late 80’s. The styli for F14 and LEVEL II are different LineContact type and MicroRidge and cantilevers are also can be Sapphire, Beryllium, Boron, Ruby.

Grace LEVEL-II LC-OFC is also superior to any other Grace models, as a final attention to detail, even the output terminals are constructed of LC OFC copper. This meticulous care and attention given to every minute detail in both the vibration and generator systems has resulted a significant improvement in the performance and sound quality. In other words the Grace F14 and LEVEL II are luxury models.

But I can’t see anything special in the specs for ADC-26 IM cartridge:

Output: 4mv at 55 cms/sec recorded velocity

Tracking force: 0.7g

Frequency response: 10Hz to 24kHz +- 2dB

Stylus: Elliptical contact 0.3 x 0.7

Cantilever: Aluminum

Channel Separation: 30db

Compliance: 50cu


What i can see in the original ADC-26 manual is the $20 price for the stylus exchange. This ADC was designed and made in the 60’s. The cartridge was relatively cheap and it looks like very cheap cartridge with mediorce specs and material used (cantilever, stylus tip, cartridge body). Here is some info from the Japanese source.  



Perhaps the f-14 stylus sound better to some people, but if it get to to the body of voices and musical sound of instruments it is getting very close.
I don´t want to judge what is better.
But without any question the ADC has the more bodied sound, which doesn´t sound wrong. 
The ADC is an GREAT PERFORMER!!!
Dear Raul,
I agree with you and Lucky.
The ADC 25/26 is a outstanding performer.
I use it on a Luxman PD-131 with ADC LMA-2 tonearm.
It is a really good match.
tried it with different tonearms but the Formula ADC or mayware tonearm is not the right match.
think the Adc needs a rigid but very light tonearm.
I drive it with 0,8 grams

But I am conform with everything you wrote.
Even an Grace F-9 with F-14 MicroRidge stylus (much better than any F-9 original stylus) sounds different but not better.
Perhaps it is a little more detailed, but not better. If, only a bit different.

But in my opinion you need a realy light tonearm.

All the best and greetings to Lucky Lutz.
I have a Sonus Gold Blue still in the case I purchased a little while ago.  Looks brand new.  I may have to give it a try
Hello Raul,

I haven't read the whole thread but that won't matter. I do agree that the ADC26 is a very good cartridge and I just compared it with my Sonus Gold-Blue and the differences are tiny! The Sonus is in a Sonus Formula IV unipivotarm and the ADC 26 is on a TP13 arm, both on a Thorens TD150 turntable. Both cartridges are designed by Peter Pritchard and so is the Sonus Arm. I expected a better result from the Sonus cartridge but the differences are tiny. The 26 soun ds a little more natural and the Sonus has a little more detail and soundstage, but that's it!
When I change to my Van Den Hul MC10 afterwards I really have to say that it's all coming into another dimension: much more detail and soundstage and the 'swing'-factor is a lot higher. Listening to the first Rickie Lee Jones for comparison this cartridge is a real standard that leaves a lot of cartridges behind it. You really should give that a try together with the Cinemag 3440A stepup transformers set to 600 Ohm. Enjoy it because life is to short already!!

Regards Rob
Dear friends: Last week end the ADC 26/27 was tested vs the Ortofon Anna in my system ( Saturday ) and my friend and Anna owner the Sunday.

The results were similar as with the other today LOMC top contenders: nothing for what the ADC could " feel " something as "shame ".

Dear friends: After talked with the designer of my ADS I decided to take his several advises and to make those up-dates I unfortunatelly need money and even help about.

Contrary to my desire I will put on sale one of my beloved ADC 26 with the guarantee of its mint operation condition and extraordinary quality level performance and before I put on an official auction here and everywhere if any one of you is interested to enjoy this kind of quality level just can email me here:  rauliruegas@hotmail.com

Dear @luckyx02: Maybe was my 1080 sample but other gentleman I know was unsatisfied with: @downunder .

Problem today with that Empire is that I already own several other cartridges that as the 26/27 I just never listened even that I own it from many years now.

Btw, I'm sticky with my ADC 26.

R.
Dear @luckyx02: Those Goldring 900 series, the Elac, AT 20SS and especially the Acutex 320 are very good performers and the humble empire 500ID too but needs a lot of hours to settle down as the Empire 1080 and I don't have the patience with this one.

R.
I owned and comparing with P.P. ones this systems: AT ML150, Grace F9L, Shure VST-V, Nagaoka MP200, Goldring 2500, Goldring 1042. Goldring 900 -920IGC, Grado Reference Platinum , Elac 796 HSP Jubilee,  AT20SLa/SS20, AT 7 V, Acutex 412/415/420 STR, Acutex 312III/315III/320III STR, Digitrac 300SE, Ortofon Super OM40, Shure SC39ED, Empire 500ID

from P.Pritchard  I own every cart, starting with ADC1 up to the last XLM MKIV "private" from 1986.
Dear friends: As I posted last nigth I was at my friend place whom is the owner of the Etna SL that I tested against the ADC 26/27.

We were there around 4+ hours and I brougth with me some of the same LPs we listened at my home.

First we listened his Ortofon Anna and the Etna SL in the top Thalea tonearm both great performers.
After that was the ADC 26/27 time and at the first evaluation LP track we confirmed ( we were not surprised for. ) what we listened at my home: the ADC 26/27 so high quality performance levels that depending of the room/system there are characteristics that are better than those top tier LOMC cartridges but exist one characteristics where the ADC is superior to these cartridges and the other LOMC I reported here and obviously better that any vintage/today well regarded MM/MI ones and that characteristic is its amazing: RHYTHM, we just dont's come back to listen to other top quality performer and when you return to it you fell that something is missed.

With out doubt these ADC 26/27 samples I own are the best and for a huge range/margin discovery/up date I experienced in all my audio life just: astonishing ! ! !

The " motor " of the 26/27 is something really special that Pritchard other designs does not outperformed in any way.

 At least one of my four stylus/cantilever in the future I will send to change it for a way better boron cantilever and a way better stylus ti´shape. I have no doubt that that will be a great improvement to an already great cartridge and deserves that kind of up-grade.

I just received it yesterday.  It looks brand new... thats a lot of years without use.  not sure how the suspension will be but it was worth a try. I will set it up in t he next few days
There is only one Sonus that never came to my radar:
Sonus Dimension 5 which is the best in that series, all lower models are often available for sale on ebay, except that one.

Another cartridge which does not impressed me at all was that top of the line ADC Astrion with sapphire cantilever.

But seriously there are two absolutely amazing MM cartridges, they are impossible to beat: AT-ML180 OFC (Boron/MiroLine) and Grace LEVEL II LC-OFC (Boron/MicroRidge) or F-14 (Beryllium/MicroRidge). For those of you who’re serious about top vintage MM should look for them as the reference! For more organic presentation the Stanton SC-100 WOS (Sapphire-coated cantilever / Stereohedron tip) and Victor X-1II (Beryllium/Shibata) are agreat too. Save your time and money and simply buy the best cartridges instead of some inferiour models from Sonus, ADC etc. If someone will tell your that some rare ADC is more expensive than the most problematic Technics cartridges, do yourself a favour and ignore it. The greatest MM ever made are all under $1500 today, most of them are under $700-1000 max, even in NOS condition. That Technics is the most expensive and overrated cartridge because of the Mexican thread, but 99% of the NOS sampes are all dead, after you will play one side of the record the cartridge almost lay down to the record surface (this is the best example how BAD is the suspension of Technics 100cmk4 or 205c mk4 cartridges). None of the vintage MM cartridges from many other manufacturers have such problem with suspension! So they are better and does not require crazy investment in refurbishing with VdH (his prices for service are the highest on the planet) who can not stay with original parts and most likely will refurbish the cartridge with different parts/material, most likely will replace the whole cantilever/stylus assemply with something different). No one on this forum can explain what VdH does with several samples of the Technics, so we don’t even know was a cartridge completely refurbished or not, but people just keep paying him rediculous fee for service. I’ve seen and owned various refurbished Technics 100c mk3 and 205c mk4 all of them were refurbished by experiences and respected vendors with completely different cantilevers/styli and that was the only was to keep them alive. Original Technic have unique cantilever (hollow pipe boron) and lowest effective mass stylus, replaceing them will change the sound! Many japanese manufacturers such as Audio-Technica made better cartridges with better styli and better cantilevers, those carts never ever had so many problems as the Technics.  

Don’t waste your time and money for retipping/refurbishing top vintage MM cartridges, they will never be as good as the originals, also the main benefit of MM design is a stylus replacement which can be purchased separately (NOS) even for some very rare models. Your MC does not have this option and this is the reason why i prefer an MM/MI/MF/IM instead of MC in many cases.

How does your Sonus Blue Gold compare to your Pickering now ?

There was another sample for sale on eBay just recently, if someone here on A´gon purchased it I´ll be interested in how it performs in his/her´s system.
Dear @downunder : For almost a year you was listening to the original cartridge till came down. As I posted my sample falls down before and I send it to a re-ttiper whom return the cartridge because he can’t fixed and was then when I remembered about the VDH past relation ship with that cartridge and was there where was fixed and that’s why I gave my advise when you look for help in those times.

I knew that the VDH fixed cartridge came with solid boron cantilever and with the great VDH stylus instead the original elliptical.

My reaction when I started to listening to it was the same you had in what you posted in that link. I was really satisfied with.

I’m not an expert building or designing cartridges, my ignorance levels about are really high so I never cared what VDH made to fix it because the subject was that the cartridge probabilities to fix it were really low so that they did it was a true achievement and as I said I was satisfied with is high quality level performance as you was.

The original elliptical stylus tip is not superior to the VdH one, the real difference is in the set up where is more easy to find out the spot on VTA/SRA/AZ/VTF in the elliptical than in the very special VdH line contact one.

In the other side no matters what if you have a hollow tube of any metal and you hit it it will sounds to " lively " against the same solid metal tube when you hit it: here the sound will be a little " dull .
The " lively " sound are only higher resonances/vibrations that means higher distortions and that’s exactly what you are listening in your today sample.

Not really better sound but a sound with higher distortions/resonances that the cantilever develops and that those cantilever tiny movements does not comes from the recording information in the LP grooves. The solid boron cantilever in the VdH work has way lower resonances and lower non-existent movements. Normally distortions sounds as more " lively "/edgy than when exist lower distortions that means more neutral not exactly rounded but neutral with better tonal balance.
That you like more the " lively " ellptical tip more it does not means is superior to the one from VdH because is not.

Was thank’s to VdH work that your today original cantilever/stylus works. I don’t blame VdH in any way because they fixed to me at least other 10 cartridges.

Btw, I owned and own several Colibri VdH samples, I bougth always the very low output of their Colibri line: 0.22mv that are the ones that performs the best.
Only with one of them I had a problem and was because my fault when the mounted Colibri fall down ( suddenly ) from the tonerm rest position to the platter/LP TT.
I have to say that the Colibri rides too low and is very sensible to mishandling it even when we need to clean the stylus tip. If we do the clean with no full care about we can easily damage and suspension collapse but other than this the Colibri is a first rate performer and hard to beat.

In other order of ideas those MAXX 3 and the whole room/system quality level performance will be benefitiated with the integration of two powered subwoofers and running the MAXX’s through a high pass filter. Not looking to chime about, only an advise. for the better.

Yes the Elac is very good, I own the top one 896 thank’s to that MM thread.
