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:

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

This is the ADC 25:

and this the ADC 27:

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.

 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.

Sure, then why not to change the cantilever?



So I will do the same as Raul. Try to get a modern diamond from a good retip service.

It's optional, but if you agree that stylus does matter, i hope you agree that cantilever does matter too. Then summarise the cost of the High-End cantilever and High-End Stylus you're getting closer to the price of the completely different vintage cartridge with those types of cantilever and stylus already installed by original designer somewhere in the 80s. For example Grace products, if you will change just the stylus on your Grace you will upgrade the cartridge/sound. They made Boron/MicroRidge and Beryllium/MicroRidge, they are all high compliance. There is a HUGE difference between Aluminum/Elliptical and Boron/MicroRidge styli made by Grace (in my experience). So this brand's designers were smart enough to make many different styli (different cantilevers and diamonds) for their customers who would like to upgrade, so they don't need to retip or refurbish their carts with third-party vendors. Unfortunately ADC and its "genious" designer does not offer such option for his customers, no wonder why, because his ADC 26 was designed back in the 60s, when they can not even dream about Hi-Fi cartridges that appeared on the market only in the 70's and reached Ultra High-End quality only in the 80's.   

So the story about 60's ADC MI remind me a story about 60's Denon 103 MC. Owners are happy to invest more in their 60's cartridges instead of investing in the proper cartridges made with better styli/cantilevers a bit later in the 70's. There are many, but i'm not sure how many did you tried? 

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.
 
I;m surious what do you think about Denon DA-401 toneam for High-Compliance cartridges? Or Technics EPA-100 and EPA-100 mkII toneamrs for High Compliance cartridges ? Or Victor UA-7045 toneam? 

To my surprice some of the a'gon members are happy to use high Compliance MM even on Fidelity-Research FR64s high mass tonearm. I have the arm, but i haven't tried any MM on it yet. 

P.S. Where is ADC MI today ?
But this is a brand new Coreless Straight-Flux Cartridge from ex Grace engineer, interesting one (for $12 000). 


Coreless Straight Flux Cartridge.... costs $12,000?
"Inductance, secret".  Ya gotta love that.
I'm going to look for it in Tokyo in May, if I can remember the name, which by then I probably won't.
@lewm it was J.Carr you has mentioned this new cartridge on our forum first, it was last year if i remember correct. Being a Grace fan i’m pround the ex Grace engineer invented this brand new cartridge. The name is TOP WING and they made two models, this is another model TOP WING Suzaku (Red Sparrow)  http://topwing.jp/RedSparrow-en.html
To my surprice some of the a'gon members are happy to use high Compliance MM even on Fidelity-Research FR64s high mass tonearm. I have the arm, but i haven't tried any MM on it yet.

Try it Chak......you may be surprised 🤗
I had an ADC XLM which was mounted in a Grace 707...a great combination.   I had problems with the suspension failing, however, it was very easy to replace.  At the time I thought it excellent, but my components were not as good as I currently have.
