Dear Lewm: The Velodyne acelerometer/servo senses 16,000 times each SECOND the cone movements to correct any single deviation that could increment the THD.
For you can have and idea of what we are talking about think on this the very well regarded JL active subwoofers at 50hz and 120SPL at 1m shows a THD from 6.5% and 10.0% THD, obviously that at 20hz that THD goes even higher.
Been optimistic your ESL at least shows five to ten higher THD on that same circumstances and this is the kind level of distortions you can hear through those ESLs and maybe your ESL can't handle 50hz at 120SPL!
Velodyne shows 0.5% THD at 20hz!!!!!!!!!
There is no contest against no other single home system active subwoofer and against your ESL could be " patetic " to make any comparison on the bass frequency range and this sole fact makes a paramount difference by order of magnitud.
IMHO no argument can " fight " against those facts.
I think that every one of us must to take more seriously the bass frequency management in your audio system. IMHO as good this bass management as good that audio system, here is where belongs the systems differences in between.

Dear firneds: Precept 440 made by AT?, these experiences for tomorrow. I have to slep now.
Regards and enjoy the music, R. |
Nandric, my package is not lost its at Post Office according to my tracking information. "Addressee requested pick-up" since Dec. 4, which is fine as long as the post office keeps holding it. I thought it is a limit to how long the PO will hold a package, they are not a warehouse.
If I would of known the extra trouble us damn foreigners cause I would not have bothered sending it. :)
|
Travbrow, Deed you try (USA) Customs? With your tracktrace nr. they shoud be able to find your packet. That is what Lew deed with a packet that I posted to him some time ago. If I remeber well he waited for two months for this packet and was also not amused. However his packet was by the customs all this time. |
Travbow,
"If I would of known the extra trouble us damn foreigners cause I would not have bothered sending it"
Give Andy just outside of Seatle a try. "Phonocartridgeretipping.com" He did and excellent job rebuilting a M/C cartridge for me with a turnaround time of only 21 days. Highly recommended by quite a few people on several forums! Regards, Don |
Don, I think it was the Pickering TL-4S, or something close to that in name, that first aroused my curiosity to reconsider MM cartridges. Yes, even before this hoary thread was started by Raul. Dave Pogue, a regular contributor on VA, lives near me, and several years ago he invited me to visit his home to audition his Jean Nantais-Lenco. Not only did I like the Lenco, I was very impressed with the overall sound of his system, and when he told me that he was using that cheap Pickering, which he purchased off eBay for under $200, I was stunned. Still, I made no move to MMs until that experience was further re-enforced by this thread. Funnily enough, I have never purchased the TL4S; I doubt it's still available on eBay. But it's excellent. I was not aware that Timeltel was a devotee'.
Raul, There is no need for you to explain to me why your own system may sound great; I assume that it may, and I would never say otherwise unless or until I had actually visited your home and had a listen. I only advise you to extend the same consideration to me and others. Other than that, I have come to think our argument about speakers is childish, and I apologize to the group. |
Dear Lewm: ++++ " explain to me why your own system may sound great.... " +++++
I think there is a misunderstanding down there because that is not the main subject but that: do it in the right way an active " decent " pair of subwoofers integrated to passive audio system speakers, IMHO, always will gives a lower system distortions and higher system resolution.
Tha's all about.
Btw, you don't need to hear my system but you are welcomed any time. What I already told you is that in the future you can give you the opportunity to test the integration of subs ( on true stereo fashion . ) in your system. I'm absolutely sure that if you test it in the right way you will be " jaws dropped " and never will comeback to your today system status. You have very good speakers and even that you don't know those ESLs are a lot better that what you are experienced today.
Tha's all. I'm not talking of my system or me I'm trying only to help to improve quality performance level of almost any audio system of any of you. The " ball " is not in my field but in yours.
I think that this thread help to all of us when we share each one experiences and in my case almost always I test/tested many of yours experiences because is the only way to learn how make things better.
Regards and enjoy the music, R. |
Dear Raul:
"every single improvement in my system need it that I made it a whole new subs set up but when you are " there " ( " perfect " integration)"
My journey with the DD-15 sub has been along the same lines. Since last post I resolved the disjunction in timing by bringing the sub out of the corner and forward to the main speakers. The DSP set-up utility is versatile in allowing the user to adjust phase shift in small increments. However coincident timing may also be a consequence of room effects and placement issues that are less predictable than the DD set-up utility can address in itself. The long reflected wave form of sub-bass frequencies suggests that a sub's location in the plane of mains shouldn't have much to do with timing. With a sub we are really hearing the room as much as the speaker. However with improved LF articulation I do hear more accurate timing at the new position. Perhaps timing is detected more through higher-order harmonics than through LF fundamentals. This is a separate consideration from your point about IMD causing problems up the frequency range.
In addition, fierce LF vibration through the sub's cabinet walls may modulate the cabinet surface and propagate off the cabinet into the room as upper bass and mid-range frequencies. Whatever the Vel's strengths as a sub, the cabinet is pretty basic MDF that benefits from additional internal bracing and damping. I painted thick damping compound(containing ceramic silicate and brass dust)to its interior and added a Star Sound SP-1 rack. The solid coupling of the SP-1 is a big improvement over the soft coupling of a prior Auralex foam platform. I have a sack of micro-bearing steel on top. The microbearing is more reactive than lead shot and does a better job of dissipating vibration into heat. Other mods include discrete Schottky rectifiers and silver internal wiring(which IIRC you have done as well.)
I generally accord with Lew that most subs do more harm than good. When it's done right and the sub volume level is not exaggerated, it adds a satisfying skirt below 30Hz that pressurizes the room without the dreaded "thump." |
Regards, Raul: Thanks for your comments. As mentioned, there are days when my modest rig exceeds expectations and occasionally keeps me captivated into the early hours. There are other sessions when the components seem to not want to have anything to do with each other.
Although not exactly given away with a purchase of ten gallons of gas and even though the subwoofers are nicely timbre matched to the speakers, in comparison with the alacrity in transient behavior and definition the mains are capable of, and if specific attention is given, the DSP 3200's simply fail to keep pace. This is heard as overshoot. Not of the Signature series, Paradigm appears to have given more attention to rise time and range (23hz, extension to 18hz) than to quieting excursion at termination of signal.
If opportunity to audition the Velodynes is presented it should be interesting. The figures you give for distortion are, for a subwoofer, very impressive.
Looking forward to your impressions of the Precept, IIRC the 440 is ML/beryllium?
Peace, |
Nandric, I don't think you understand. I know the package is at Axels PO, he just did'nt pick it up since DEC. 4. He needs to pick it up, that's all!
If he already did and my tracking doesn't show that,than sorry for these posts, but he never acknowledged that he did. |
Lew, not to speak for Dave P but I'm fairly certain the Pickering you referred to hearing several years ago is a TL-2S. I have one also and find it generally in the same performance ballpark as my Stanton 881S...which is to say it's very good. If I recall, Dave P expressed preference for his Tl-2S over his 881S...my own preference is reversed. I still have the Pickering though and look forward to hearing about that 4S :)
Jim |
Lewm,
I have seen the "1's", the "2's" and the "3's" for sale on ebay but never have I seen a "4". I own a 981LZS and a 981HZS. I thought this DTL-4S just might be a nice addition to go with either of the 981 bodies. I have been for many years a Stanton/Pickering fan. Had a 881S back in the "70s". Turntable was a Philips GA312. There was/is a lot more for that cartridge to give than what that table was able to provide. Great T/T though. I still have it and do use it ocasionally. Current cartridge on it is a Empire 2000E with a LPGear 4000DIII stylus. Regards Don |
Dear Dgarretson: Even that IMHO my Velodynes are " right there " with the last change of those SR20 fuses I had to re-set one subs parameter: SPL.
The change was so dramatic lowering self subs distortions and as consecuence room self ditortions that now that the subs perfromance are really clean my ears perception noted that as a lower SPL but in reality there was not lower SPL but that now the before subs/room generated added distortions disappeared ( in part. I think that always we have to live with some distortions levels. ) and ears are extremely sensitive ( because our bass brain/ears perception is the one that suffers more from our aged life. ) and I heard lower distortions but lower SPL too so I adjusted the SPL owns subs cobntrol and that's and now with this fixed SPL parameter the quality improved more.
We don't know how much information exist in the bass frequency range because those bass generated distortions and because even with out those distortions is not an easy indentify the bass ( low bass. ) fundamentals in cleAR/CLEAN WAY WITH ABSOLUTE DEFINITION IN EACH BASS NOTE. Today I'm almost totally aware of that bass information.
IMHO we can't do it with out a right subs integration to the audio system. It is impossible to achieve it because the THD and IMD preclude it.
All what is generated my the subs/speakers suffer normaly added distotions due to the room interactions so my first target is to lower any kind of distortions in the audio system to facilitate a better system/room integartion with lower problems and more easy to fix those problems.

There are other sessions when the components seem to not want to have anything to do with each other. Greetings Professor, I know what you mean and I sympathise. This last week.....for the first time in a year....my phono-stage has been destroyed by the vagaries of the power grid. And this...despite the fact that I installed a Shindo Mr T power conditioner for the turntables and preamp since this last happened? To hear the soundstage collapse taking with it, the transparency and emotional content is heartbreaking. At these times it is hard to reconcile the beauty and 'soul' which one listened to only yesterday....with the hard-edged brittleness akin to the worst digital reproduction? I can perhaps understand the vagaries of the electrical supply in the wilds of Kentucky :-).........but in the midst of a metropolis of nearly 5 million like Sydney......I am aghast. In my system this phenomenon seems only to attack the phono-stage.....leaving the line-level inputs untouched? I believe there is a case here for the Discrimination Commission? I hope your occurrences are not often? |
Regards, Halcro: Condolences, Henry. Having given it considerable thought, there is a suspicion of meteorological impact. Living in the "sticks" is a dubious advantage, have my own personal transformer & the old rig is on a dedicated twenty amp line, voltage swing and noise in the line are not excessive.
Observed is a limbering-up period of a half hour and the expectation that a cart that has laid idle for a while will need some run-in. Listener's (re)acclimation may contribute. For those who enjoy speculation, as a cartridge is an electrical generator, some degree of Joule heating is another potential candidate. The correct perspective is that resistance also depends on temperature, usually increasing as the temperature increases. For reasonably small changes in temperature, the change in resistivity, and therefore the change in resistance, is proportional to the temperature change.
In the U.S., voltage at its peak hits about +170 V, decreases through 0 to -170 V, and then rises back through 0 to +170 V again. 120 volts is actually a kind of average voltage, the peak really is about 170 V. It's not difficult for an armchair theoretician to anticipate severe spikes in voltage frying a resistor, hopefully your repair will be an easy fix.
In 2009, the U.S. midwest experienced a severe ice storm, service was interrupted to tens of thousands of customers. Here, it was necessary to rely on a generator for eleven days before power was restored, consideration was given to surges as service was reconnected. Did a little research & obtained a power conditioner with battery backup, a Furman F1000-UPS Uninterruptible Back-up Power Supply unit with non sacrificial surge protection and 120v regulation within 5%, protection rather than regeneration was the concern.
Will proceed to compile data on barometer, humidity, ambient temperature, planetary alignment & regular consultation of the crystal ball.
Hope you get your rig up & running quickly, otherwise, still listening to the Virtuoso?
Season's best & Peace, |
Regards, Griffithds: Following your saga of the TL4S with interest. As reports drift in, looks like the TL series may be a winner. It's interesting that the PickeringUK site identifies it as "line contact", can you confirm the "S" designation refers to "Stereohedron"?
Peace,
|
Good Morning Tom,
I have sent an email to PickeringUK asking them about that very question. I have bought several stylus's from Turntableneedle.com and know them to be a very reputable supplier. I am confident that what I'm about to receive from them will actually be an original Pickering styli. I'm wondering if when Pickering/Stanton moved from New York to Florida, if they started replacing the "Sterohedron" with a "line contact"? It would have been a lot easier to obtain. I'm reminded of the fact that their move to Florida was a cost cutting move. One more point to conceder. There is no mention of a line contact stylus in Richard Steinfelds handbook. His publication follows Stanton/Pickering cartridge/styli manufacturing during the "Golden age of analog". This would be up to but not after the Florida move. I am not doubting PickeringUK statements about selling original Pickering styli. But I'm beginning to think that a lot of what's being sold by PickeringUK was manufactured after the Florida move. When Stanton/Pickering went "disco". Regards, Don |
Tom,
Just received a reply from Turntableneedles.com. It was a confirmed NOS Stereohedron styli. Still waiting for PickeringUKs reply.
Regards, Don |
Tom and all interested. The folowing is my question and the reply from PickeringUK.
__________________________________________________ Reply: Stereohedron is Pickering's name for their line contact tips.
-------------------------------------------------------------------------------- From: griffithds@jaws.bz To: eSales@PickeringUK.com Subject: Stylus question Date: Sat, 15 Dec 2012
Good Morning, You have a DTL-4S for sale stated as a line contact. I have a original Pickering DTL-4S that is a Stereohedron. Is the difference between the two styli a matter of mine is from New York plant and yours is from the Flordia plant? If there is some other reason (unnown to me), for the two styli profiles, both being a DTL-4S. Thank you for your reply in advance. Regards, Don Griffith ____________________________________________________
First time I have ever heard of a Stereohedron refered to as another name for line contact! Shibata, yes, but line contact? |
I have now posted twice in vain. Neither post appears here.
To repeat: Jim, You may well be correct, 2S, not 4S. Timeltel, Have you really documented 170VAC at your wall socket? That's a real indictment of your power company, but it is not typical of the USA as you suggest. Living all my life in the NE corridor, I have never ever seen or heard of such high AC voltage. Nor has anyone else ever reported similarly high voltage. So I think the situation is location and power company dependent. The highest I have seen in my home is 125V. The lowest about 117V. Raul, If you will supply Guillermo with my email address, I will be happy to discuss with him ways in which he can dramatically improve his 845PXs, some of them quite simple and cost-free. |
Regards, Lewm: That surprising bit of data is from Boston University, Department of Physics. In the most sincere manner possible, if anyone can supply other figures it would be appreciated. AC is measured on a time scale (Hz), cyclical & there is an average at the receptacle. Here it averages 124v AC. A quote, again from Boston College: "Voltage from a wall socket is known as the root mean square, or rms, average. Because the voltage varies sinusoidally, with as much positive as negative, doing a straight average would get you zero for the average voltage". Voltage is then an average of the range from positive to negative. BTW, 117v rms is my observed low, 128v rms for high. R(oot) m(ean) s(quare) value is obtained: first, square everything second, average. third, take the square root of the average. For a clear description: http://www.raeng.org.uk/education/diploma/maths/pdf/exemplars_engineering/8_RMS.pdfHaving dabbled around with pencil & paper for a tormented moment, the broadest possible expression is that rms voltage is a (nom) 70% of peak. 67% was a repeated outcome. As this is a square root calculation involving infinite variables, neither figure should be taken as correct. Peace, |
Correction: Statement I made on 12/10/12
"Before anyone misunderstands, the TL4S that Tom (timeltel), and I have been talking about is a M/M type stylus. That means 880/881s and above line of cartridges. Anything below, XV15, 680/681 are M/I. I would hate to have someone with a 681EEES buy a TL4S, on our recommendation, only to discover it doesn't work!"
The TL4S is NOT a M/M. It is a M/I. It will NOT work on the 880/881 and above. Anything below that line of cartridges, the XV15, 680/681 is acceptable. Just the opposite of what I stated. My deepest apppolgies to all for my mistake! I received the TL4S today and mounted it on a HLZ body. Dead quite. Nothing. That's when I started to compare my notes with Richards "Stanton/Pickering handbook" and discovered my notes were not correct. I then mounted my XV-15/750E, verified that everything was working, then swapped styli. The TL4S just creamed the much regarded 750E. More authoritive bass, greater dynamics overall with cleaner and more extended highs. This was with "0" hours of break-in. The best Stanton/Pickering M/I that I own is the Stanton L747S (D74S stylus). Stanton only had one M/I above it and that was the L847S (D84S stylus). I have mounted the TL4S on the L747S body. No contest there either. Easily bettered the highly thought of D74S which BTW is also a Sterohedron styli. I now have just over 7 hours on the L747S/TL4S and have to state, this is one hell of a stylus. My posts have been taking 12+ hours to appear on this thread so by the time you read this, I will have compared it to Stanton's top cartridges, the 981 LZS and the HZS. This stylus is definitely a winner. Regards, Don |
Dear Giffithds: Shibata, Stereohedron and several other cartridge manufacturer stylus as the analog6 from AKG and the like at the end was not eliptical but more as line contact with " superior "/wide contact groove. There are several manufacturer " line contact " versions. It's right the name " line contact for them ? well is IMHO not important what is important is that as the Shibata or the analog-6 or even the MR the Stereohedron has a wider groove contact.
What is more complicated is that some manufacturers had 2-3 versions of the same stylus shape where some of them disclosed it but other noprmally did not.
Btw, I already bought a DTL-4S in NOS condition for the non-Pmount Pickering cartridge version. I think could be a difference aginst my XV5000/981 or the 7500 that are S2 versions on the stylus shape.
Could be a quality performance diffrence in between the S2 and the S stylus versions?, we will see when I have on hand but you already own all those stylus shape versions, could you share with us the differences that you experienced on the 981 ( H ) with the TL4S against the 981 native one stylus?, thank you in advance.
Regards and enjoy the music, R. |
Dear Halcro: It's weird what happen with your DM10 because normally that kind of audio level electronics were designed to protect the differeent stages against that kind of events and many others. I understand this is the seond time in the last few months that your DM10 ( for different kind of events. ) was out of work. I don't like it that situation and maybe is time to think in the possibility of a change of Phonolinepreamp.
Regards and enjoy the music, R. |
Thanks for the recommendation Griffiths, unfortunately I can't send the P100CMKIV anywhere because I don't have it. I sent another email to Axel to ask for acknowledgement if he picked up my cartridge and stylus. Will update on further developments, funny he answered all my emails when I inquired about sending the cartridge to him. As of now I would not recommend anyone send a valuable cartridge to Axel. |
Raul,
"Btw, I already bought a DTL-4S in NOS condition for the non-Pmount Pickering cartridge version,"
Is yours the tall Stanton looking version, or the short flat Pickering looking version. Mine looks like a Stanton housing. Regards, Don |
Regards Griffithds: The Stanton/Pickering carts have me puzzled. Vinyl Engine Data Base is often incorrect, glad to have a Stantering Guru on board. That would be you, Don.
Thanks for keeping us informed.
Peace, |
Griffithds, have you tried the TL4s cartridge with it's own stylus? |
Hi Acmam3
I have not tried a TL-4S cartridge, but I do now have my eye on a TL-3 body. What I'm trying to determine is if the TL-(X) bodies are any different than the TL(X)S bodies. Until Timeltel mentioned the DTL-4S stylus, I had not given the cartridge line much thought. I owe Tom a thank you for mentioning it in a previous post, thereby peeking my interest. From Richards handbook, it appears the TL-(x)S cartridge "bodies" are all the same. Only the stylus quality being the deciding factor for improvements in the "S" line. I am quite awe struck with the DTL-4S stylus top flight performance. I think it being thought of as a "P" mount type, has allowed most of us to overlook it. That is until now! Regards, Don |
My post Dated 12-16-12 took 17 hours to get printed! Moderator states 4-8 hours. When is the high speed improvement suppose to take effect? |
Dear griffithds: Stupid of me because now I will have a Pickering stylus with no cartridge to hear it.
I'm not angry with your wrong statement that I followed but with my self because I always make a research before I to take any single audio action but this time. My mistake was the Richard reference you did because he is the real Stanton/Pickering guru ( that I know him very well through Lenco forum. ) and if he was your reference then I take your statement for sure.
Never mind as I said was my mistake. I hope that in the future that error by my self could give me some reward: who knows?
Regards and enjoy the music, R. |
Raul,
Over the last few years, I have been following various forums discussing the Stanton/Pickering cartridges. I have a little note book on just them. Before the Richards handbook, the only information/knowledge I had was from my notebook of statements made by forum members that I trusted or just felt had correct knowledge. Richards handbook greatly added to that data base. I also bought the stylus thinking (from my notes), that the M/M line is what this stylus supported. Once I realized something was wrong, I went looking in Richards reference handbook for answers. Thumbing thru, I found nothing pertaining to the TL line. I had to reread the handbook from page 1. When I got to page 48, at the bottom of the page is a small list of cartridges/styli with cross-References to the line of like Stanton/Pickering cartridges. The TL-4Super cross-ref. is to the Stanton/Pickering M/I line. This little tidbit of information is the only mention of any of the TL line of cartridges. Like I said, I had to reread the entire handbook to find it. I have proven it to be true. There are two Stanton Guru's (ex employees), on that forum you reference. They both readily admit to not knowing everything but they are far more knowledgeable than I. For you, this cartridge journey will be like the Goldring G800. Cheap body (Stanton/Pickering M/I series), with surprise stylus (DTL-4S), = goldmine. You will not be disappointed. Regards, Don |
Raul,
Do you know how to correct data on the Vinyl Engine Cartridge Database? It states all Pickering TL-(x) cartridges are M/M. Lets not allow history to repeat itself! Regards, Don |
Dear Professor and Raul, Sorry to give the impression that my phono-stage is 'down'.........I was merely sympathising with the Professor's frustrations at his system sounding poorly from time to time? My Halcro preamp is working perfectly......however last week.....outside work on the power cables caused havoc with the 'sound' of the built-in phono stage despite the intervention of the Shindo power conditioner? All is back to normal at present :-) |
Update, Axel sent email explaining the situation. Things work a little different in Germany. He picked up the cartridge at his customer office after receiving letter notifying that package is there for pick-up. He needs to drive 60KM to pick-up his packages.
I am confident that every thing will go well. Just was confused about the tracking info and the different way Axel handles his mail. |
Dear Griffithds: I understand what happened there. With cartridge manufacturers like Empire/Stanton/Pickering/AT/Signet/AKG/Acutex and the like there are always some kind of mix-up. In this same thread almost all of us time to time made it mistakes because so many different cartridge models of those vintage manufacturers and no one knows everything of everything especially with this " new " vintage cartridges. I remember " problems with the Empire series 1000 and 900, with the AKG too and we all know the confusion with those flat nose/long nose Acutex.
My first Acutex was a flat nose one and before arrived I bought a stylus replacement that when I received was for the long nose version but both cartridges has the same model so whom can imagine Acutex designed the same model description in two versions????
After some errors from my part I took the task to research always before take action but this time I did it but maybe even with that research could be happened the same.
As I said I'm not angry with you or really worried about because now a new journey started to me : the TL-3 cartridge body.
To fix the VE cartridge data errors I think you have to put in contact with them and in specific with the persons that mantain that data bases.
I don't receive yet my TL4S stylus replacements but I saw at the picture is the flat Pickering version.

Dear Travbrow: Good, now you are " calm " because with no answer to our email we go on " desesperation ", at least is what happen to me in that situation.
Regards and enjoy the music, R. |
Dear Halcro: Thank's for the clarification about. I was thinking something really bad because even you started a thread only for that " event ".
Regards and enjoy the music, R. |
Dear Raul, Even your errors have value for us. The stylus error in particulare has the therapeutic value. I bought at least 8 single styli but actually thought that this is very smart thing to do. Those are namely much more difficult to get then the 'bodies'. I have no idea how to write the plural by corpus.
Regards, |
Regards, Halcro: Humidity at 76%, barometer is 29.66 millibars. Outside temp. 48F, foggy this morning. Elec. service is holding a steady 125v. Old rig is cranking out out some pretty good soundstage, dynamics & ambience.
Running in an AT ML150 OCC on a Yamamoto HS-2, bronze plate above cherry/10.5gm mass. Crystal clear optimized line contact on ruby. Sounds good, Soundsmith does beautiful work & everything's "in the groove".
Turning over every stone for a DTL-4S, have both XV-15 & 681 MI generator bodies (thanks for that info, Don), keeping a sharp eye out for a TL body. Vinyl Engine Data Base is a WIKI, caveats apply.
Horoscope says Justin Beeber loves me today, crystal ball says if your name is Henry it's a good day for vinyl in Oz.
Life is good, best wishes for this holiday & any other season.

Timeltel: To quote Wikipedia: "Because of their usefulness in carrying out power calculations, listed voltages for power outlets, e.g. 120 V (USA) or 230 V (Europe), are almost always quoted in RMS values, and not peak values."
I know all about RMS. Breaking down the AC into maxima and minima is not really to the point, if you are worrying about over-voltage frying your gear. It's RMS that counts. If your RMS voltage goes well above 120V, it is a given that the positive going peak of the sinusoidal wave form will also have gone way up. I guess you know this; I do too. I think I just mis-read you original post on the subject.
By the way, you guys would get into a lot less trouble, if you would only stick to the stylus assembly that the audio gods intended for use with your particular cartridge. |
Tom, The following quote is from a person on the Lenco forum in reply to a question I put forth to Richard. What he has said sort of snaps everything into focus.
"Your Stanton L747S, and the other L7x7 models: Stanton 680 in a P-Mount. Exact model designation differs according to stylus.
The equivalent Pickerings are the TL series which are the Pickering XV-15 in a P-Mount. Exact model designation (TLE, TL3-S, etc.) differs according to stylus."
Save yourself some money and just get the stylus. You already have 2 usable (identical), bodies.
Regards, Don |
Dear Lewm: +++++ " By the way, you guys would get into a lot less trouble, if you would only stick to the stylus assembly that the audio gods intended for use with your particular cartridge. " +++++
yes, less problems but less learning/discover " new and exiciting " experiences too.
My latest 981 HZS experiences confirm my statement because thank's that I'm not sticked to the 981HZS and tested with the 5000XVS many of us learned about.
I think that each one of us are looking for the " best " we can achieve and that's why some of us are hyperactive on that subject.

Nandric, "Corpora", or "corpuses" will do. I think it's a second declension noun in Latin. |
Regards, Lew: Apologies for not having qualified that figure, leaving you in the position of an informed audio enthusiast deliberating the merits of a Soundesign "1,000 watt Peak Power" boom box at the supermarket.
Peace, |
Regards, Griffithds: Thanks again. A reminder, the painted white, gray, then silver and gold XV-15 motors are of increasingly tighter spec., calibrated 681 bodies (this also implies a lab-matched stylus) will be engraved with a registration #. Twin sons from different fathers, both are four coil generators.

Thanks, Tom,
I will be looking for some Gold XV-15 motors. This DTL-4S is the top "P mount" Pickering stylus. Would not its twin be the top Pickering stylus in the XV-15 line. Is that not the XV-15/1800S! The Stanton twins to the TL line/XV-15 line was the 681 solid mount and the L7x7S "P" mount. There top stylus was the 681EEES and the D84S. You and I have a D74S which is a step down from the D84S. There is no doubt in my mind that the DTL-4S is better that the/our D74S. Like is said earlier, this DTL-4S is a winner. Thank you for bring it to my/our attention. Quite a find and I'm looking for another! Regards, Don

Dear Griffithds/Timeltel: I decide to go for the TL3/4 cartridge body for my TL4S stylus. As Lewm said it: it was with those cartridge body the designer intented the best of both.
Stanton/Pickering are so " wide " in models that intent to test an almost " infinite " stylus alternatives in between could be not only " boring " and time consuming but maybe with small rewards for the huge " job " to do it and remember that to do it we have to buy cartridges/stylus.
I think that I will stay " calm " about Stanton/Pickering with my two Stanton 981 L/H version , the Pickering 5000XVS and the TL-4S.
Is there any reason to go on with? , I think not.
Regards and enjoy the music, R. |
Timel, I love those car ads that tout a "500W" Bose stereo system. Of course, Mr. Bose or his heirs are laughing all the way to the bank. The lay public does think that the more "Watts" the better it must sound. |
