@dady

thank you for your trust in my abilities to give a score….

I can tell you what me impressed on my way since 2007 here.
First combination that was a hit was ZMs Pumkin pre and F4 combined.

I sold my Accuphase for this combination…. -:)

and the second hit was BA-1 combined with Pumpkin.

Then the fever was starting, F1 and F2 were only a short time active, next impressive stops were J2 and M2, really all time favorites.

And F7, as far as I could clone it from the 6moons pictures was the sunlight of this year.

The Aleph30 was interesting for me to go away from push-pull again to more pure class A.

I tried several times to clone the SIT-2, but i had some difficulties to adjust the amp to the
10W output. The SITs really have a special sound, so innocent and pure…… :)


But I returned mostly to the more powerful amps.

Most of you know it meanwhile, I have only one case, so I cannot really compare the amps at the same time. And remarked that I get used to the sound of amps after some time and with good music, so I enjoy most of Nelsons amps. The score is mostly how long they stay in the system or how often the come back from the basement in the hearing room…. :))

I tried some other concepts (very powerful class AB amp, 200W) as well but I did not get this relaxed pure and natural sound Nelson amps have.

Sometimes I am a bit ashamed that I can tell you how the different FW and Aleph amps interpret certain songs. But I cannot tell anything about the real musical details, rhythm or melody or notes etc. And I ask myself if I shouldn't care more for my understanding of music than for the electronic side.

The Aleph30 is not as dynamic as the BA-3b mono block for sure, but you can dive at good levels in a very homogeneous sound with nice colors and have fun.

The 2SJ313 deliver a bit more detail, but to my ears the 9610 make the more fascinating sound, maybe less correct.

my Golden Ear Generg is part of small German group of buddies, which in same time is having opportunity to dissmantle majority of original Papa's products,while in same time being extremely ethical ,keeping that info in own circle ... entire operation being for their personal pleasure and growth

contrary to no small number of leachers ,making money with blatant clones ,above and under the rug

Thanks my dear friend.
I have an Aleph X I got from another constructor of Barcelona. The sound is tight and just. I listen with a horn loaded full range. With chamber music is incredible reality but with symphonic one probably the presence of intermodulation or the richness of harmonics interacting degrade the musical program. That's true that is impossible to listen for long time that kind of music.
Now is my only amplifier on service (class A) and with the pass of time we became addict to this class of service. A soon i finished the other amps projects I will navegate inside of my X amp to tune something inside. One idea is reload like two Aleph 30.
I got with Jama, hundred 313 for make matched pairs for this configuration. But for thousand of reasons they are in our basement. Any special Is-Vg you could consider acceptable for improve the linearity?
Thanks again and best regards, and such a surprise with the Pumpkins...

Ears are still normal color and most I know was guided by Great Aleksandar......... Who lives now with his horse and his family since a long time in Serbia......

:))))

Did you ever get the chance to listen to a pair of 2SJ74 jfets in the Aleph's frontend? How about aleph-x?

Rodeodave, yes I listened to the 2SJ74 Frontend and when I had to make the final decision for the lonely island I still prefer the 9610.
Matter of taste!

Not Aleph X, but variants of XA30, they set marks in power and relaxed reproduction, some FWs may sound sometimes more stressed.

But, sorry, as I tol,d there is no best for me, I am afraid I would even hear a "bad" amp, when the music is good....:))

I know what you mean! The brain has an amazing ability to compensate for lousy amplification when interpreting of a beautiful piece of music especially when it is known by the listener.

I suspect that the partial information being transmitted to the brain by poor reproduction is being enhanced by the emotional memory encoded when the piece was originally experienced. Even if the highs aren't being accurately reproduced, my brain knows how they should sound and to some extent constructs that memory when I get lost in the music.

I think my coffee kicked in. :D

:cool:

the connoisseur was late permaneder. I got one bottle of his stock over a friend one year later after a remark of permaneder and my reaction here in the forum….

you see Dennis it helps….but it seems he needed a lot of help…. :)))

I think permaneder would be happy to hear that the bottle finally came to Mr. Pass!

Very nice stories; thanks for sharing.

Mr. Pass stated on post #9 that the 2SJ313 is the preferred part
but "comparable modern mosfets" can also be used.

Has anyone tried the modification using FQP3P20? I assume it should
be, at least in theory, non-inferior to IRF9610.

Enough chat about the wine.....

Exactly Aleksandar, Mr. Pass brews something new with the hokey pucks.
Looks like a symmetric Toshiba Frontend and on both sides this time not the usual multiple IRF but the IXYS Monsterfets.
Looks very interesting and thanks for the insight Mr. Pass!
Seldom insight, so close to the objects of greediness.....:))
