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,
R.

Dear chakster, also ''exotic'' MM's are MM's. I am sure that you
will have no problem if, say, AT 170-180 styli will cost even more
than$500 (grin). Our Mexican friend (the fast one) mentioned 
''edr 9''. I never succeed to get one when this one was ''cart of
 the month''. This means an ''rare animal''. Those are never cheap.
BTW this ''speedy Gonzales'' was faster than I while it was I who
discovered the source for 26/27 styli. He is obviously more modest
than his other compatriot (grin).  


If I am right the ADC 25 has much higher compliance then 26/27.
I own two samples of 26 but both with doubtful styli. My proposition
is to exchange one of my 26 for an good 26/27 stylus. Not 25 stylus
because of compliance difference. 
Cardani, As J. Carr explained the advantage of an 
aluminum cantilever is that the stylus can be pressure fitted in.
To retip my 26 would mean gluing an stylus instead. This is 
done by cutting the existing cantilever and than gluing the new
one on the restant of the old cantilever. I have done this once but
never again. Besides the suspension is very difficult to fix on
those ADC's . I have seen new 25 for $100 but will try to get
an 26 or 27. 

Boron cantilever+ micro ridge stylus for the ADC 26?
Chakster will be happy : at last hollow boron cantilevers...
Those are needed to put iron rod in the cantilever. ''MI '' you
know?
Dear cardani ''the retipper give me different options ''...
As far as I know the only option is to glue new cantilever/
stylus combo on the restant of the cut off old cantilever. 
I have , alas, no idea how the suspension by whatever MM
cart can be (re)done. What other options do you mean?  
cardani, If I remember well there was  distrust in our forum against
''Bluz Broz'' styli provider. But I found on their site ADC 26 for
$123 and 27 for $126. Difficult for me in Holland and you in Mexico
to judge but our ''American friends'' can provide the needed info.
I hope that import duty in Mexico is lower then in Holland (33%). 
The problem of ''stylus only'' retip by ADC is that those styli are
''pressure fitted'', No idea how those can be removed . All other
are glued in te cantilever so those can be removed with solvent
like old cantilevers from the ''joint pipe''. One can see by all
retipped MC carts that new cntilever is glued in the ''aluminum
tube'' (aka ''joint pipe'') behind the new cantilever. Those can't
be glued in if the old can't be removed.



An possible important discovery. I inspected my both 26 styli 
with my (hand) microscope.. To my big surprise  I have
seen similar ''construction'' like by MC's. The aluminum cantilever
with the stylus is installed in the ''pipe'' behind which may be
the iron part of the construction. It is like ''joint pipe'' by MC kinds.
If the cantilever can be removed from the ''pipe'' behind than,
like by MC carts, an new cantilever /stylus combo can be glued
(?) back in the pipe behind. So even an boron rode can be 
installed this way. The parts involved are very small so only
an good retiper can answer the question if this ''surgery'' is
possible. 


Dear chakster, your pictures are much better than my description.
I also own two sample of TRX II one with Berillium the other with
saphire cantilever. Both are in excellent condition so no reason
for me to inspect their construction. But the old ADC's have such
small cantilevers that one can't see or assume ''double'' tubes.
There are btw no theory free assumption nor experiments. 
Because I assumed one piece cantilever I needed ''place'' for
iron part of the construction. As in some other samples piece of
iron is put in the back side of the cantilever . That is why I though
to make you happy with hollow boron cantilevers . Where else
could be this IRON ''ingredient '' be put? 
Anyway your beloved TRX can also be retipped with boron+
micro ridge stylus. What more do you want ? 

Dear cardani, we are moving very fast with our discoveries.
I just discovered that ADC 26/27 can be retipped but ,if 
possible, for about $500 . Then I discovered original (?)
styli for much less. I already asked my (forum) brother
Don to check and buy for me the 27 stylus if available. 
I see that you are even faster. As far as I know nobody
is faster than speedy  Gonzales (grin). Not to stay behind
Mexico's import duty I arranged with my brother Don that
he should pay Bluz Broz for me and post the stylus as 
present to his brother. No import duty at all. 
While cardani was faster I hope to compensate by being smarter.
I ordered  via my brother Don both styli 26 and 27 . I  own two
ADC 26 and will keep the one with better stylus. The other will
compensate the total cost. Smart or not? 

@chakster

 ''Astatic is not in my list, buddy''.

Well the carts are made by Mitachy  Corp. in Japan for Glanz and

Astatic. If I remember well on your Glanz 61 there is also Astatic

mark,

Dear chakster, The curious thing is that we somehow own the

same carts. Even more curious is the fact that I started this

hobby in the 70is while my first cart and arm were ADC 25 and

Pritchard. Back then I thought that nobody in the world could

compare with me. Later on I discovered that this Pritchard arm

was worthless as well any other tonearm meant for high compliance

carts. For some unknow reason cart producers competed with

each other who would achieve the highest possible compliance

but without any consideration of the question  if there are suitable

 tonearms for them.

As is in ''general'' known the cart producers never achieved any

standard whatever. 

In my opinion the only possible tonearms for those  carts are

the linear tracker which I, alas, never owned .

Well at present I own not one but two TRX 2. The later one

with ''improved'' beryllium cantilever. This ''ADC'' with quotation

marks is made by an Japanese as you already mentioned. My

quotation marks are ''caused'' by this fact. Well to me this TRX2

is , say, equal to other of our ''best ever'': AT 180, Signet TK 7cl,

JVC X1-mk 2 ,etc. Except ''of course''  your own and only

Glanz&Astatic 61 (grin).

BTW I know that there persons who search for their identity

while I am convinced that each individual in the known universe

has his own unique identity such that there are no two identical

persons in the mentioned universe. However ''Herr Freud'' invented

this theory according to which there are 3 of us in each of us: ego,

super ego and ''it''. Our moderators obviously believe this theory

so I got one additional identity from them called Nandric 3. This

Nandric made only 154 contributions in this forum while , probably

the ''super one '' made more then 3000 . So my dear co-members

you got an new member.

@chakster , I know that you know everything better but my

former self participated in the old Glanz thread. We all thought

back then that Glanz and Astatic where different animals.

Till we discovered  that both were importers who ordered their

carts by Mitachi corp. in Japan the inventor of ''magnetic flux''

technology. The only difference was the fact that that Glanz

ordered also elliptical styli for their  top range carts. Lucky me

I already wrote about identity. As you pointed out I mentioned

Vienna, Wien, Wenen and Bec 51 times.  Those are different names

but with the same reference. So regarding the question ''who

made those carts''? there is no question about: Not Glanz nor

Astatic but Mitachi. If you look at your extraordinary Glanz MFG

61 you will see on the ''nose'' of the stylus holder Astatic logo.

It is a sign like  A-- with a leg . I thought then that even Mitachi

was confused reg. the question for whom they made this 61.

I checked my Glanz and Astatic samples and can state that

Glanz has not its own logo while Astatic has. This logo you

can see on your MFG 61.

Well I think that the ''creator'' of the MM thread want to start this

thread once more to begin with the oldest (possible) carts. He

owns if I remember  wel +100 sampls so we will probably return to

the so called ''carts of the month''.

''histoire se repete'': ''the king is dead long live the king''.

Chakster what kind of (state) function do you have in mind for your

''buddy''?

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.


  

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''.

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 , 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. 

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).

@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.

I totally agree with my brother chakster that the primary

function of our forum is exchange of information. I am also(?)

multi- lingual and able to follow many international sites.

One of the ''richest'' is the German ''audio-markt.de''. The

most cartridge offerings are MC kinds (10 pages). The MM

kinds are much more ''modest'' but I have just seen offering

of ADC 25 styli for 199 euro. The plural means all 3.

I understand confusion and different valuation of cart prices

but my ''speculation'' is based on ''old MM thread'' . Each

cart of the month sky rocketed in price after Raul's recommendation.

I hope the same because I own this precious ADC 26.

Something like saying: ''history repeat itself'' (grin).

Sorry my brother (grin).



Very curious! I listed one of my ADC 26 with brand new stylus on

A'gon for longer than one year but got no offer whatever. I mean

''curious for the best cart ever''. 

The added problem is to find ADC 10E- 4. which is even better.

Not to make logical error ( Peter is the longest guy in the class

but Chakster is even longer) I mean ''according to wolfie '' and 

not according to Raul (grin). 

Well if you ''don't want to read'' no wonder you missed Raul's post about

Sonus. If Sonus was better he would not  proclaim ADC 26 as the

best. There is obviously  no such thing which is even better than the best.
