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:

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:

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,
R.

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.
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!!!
@chakster I know the LevelII and the f-14 but they are not easy to get in Europe.

@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 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.

@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
@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

@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"

@rauliruegas 
Yesterday I did a little try.
Had a look on one of my ADC 25 styli and a Sonus Gold Styli (Pathemax diamond).
So I changed the ADC cantilever with the Sonus cantilever. It fits. Perhaps not perfect, but enough to get an impression how the ADC works with a sharper diamond.
What should I say? Yes it is better than the original diamond. So I will do the same as Raul. Try to get a modern diamond from a good retip service.

About the thoughts of some here. The ADC 25 couldn´t be that good etc....
This is no expensive cartridge. If you own a lightweight tonearm just try it! You will be impressed for sure.

But I also understand you. Couldn´t believe it too a few years ago. Tried it, but only on an Technics SL1210. It was good, but the tonearm didn´t match the cartridge. Now on the light tonearm it is just wonderful.


Cheers
@chakster 
I changed the diamond including cantilever, sorry if I described not in the right way.

For sure the stylus shape was fine and modern in the 60s. But even if I get another cantilever with a "state of the art" stylusshape it will be much cheaper the a Grace or something else (I bought my ADC a few years ago for about 50 €). I all ready own 3 F-9s.
In my opinion the generator is very good (but heavy). I hope the ADC would benefit a lot.
You are right. It is a little bit of a shame ADC and Sonus didn´t go the Grace route with a lot of different stylus. Not only as upgrade but also as a perfect match to your own listening routine. But it is like it is.

I am sorry,  I know these tonearms but never tried them myself.

The ADC was good on the 1210, but is much better with the right tonearm match.

At the moment I don´t know where the prices are. Haven´t seen one or a longer time. But I am sure you could find a bargain. Think the ADC 25 was produce in not too low numbers.


These new "Grace" artridges look nice, but they are way out of my budget.


@stringreen 
the failing of suspension is a common problem with the later ADC.
Not with every stylus but can happen. I also had an XLM and ZLM (also very nice for vocal jazz etc.) with the same prob. Other XLMs and ZLMs I own don´t have the prob.
