DIY Aleph-X Vs. The real thing?

[mtj]

I recall reading someone was going to mail Nelson there DIY Aleph X a while back for him to compare it to the real thing and get some feedback. Has this taken place yet?

What are peoples opinion who have built both a stock Aleph Vs. the X version?

I'm currently building an Aleph 2 and will hopefully build an X in the future but until then I would like to hear some experienced opinions from those that have built both.

Thanks MTJ

I offered, but nelson is a busy man.
The only X amp I have listened to is an X 600.5. I can not compare that to the Aleph-X.

It depends on the skills of the person building the amplifier.
Commercial product has all the issues worked out and the
amplifier has to run a gauntlet of tests before and after burn-in.

The only person that has sent back my amps is you. Unless everone else is using them to tie up their Donzi's. What are you trying to say?

OK, I did over bias that one amp.

I heard a XA 100 and sonic signature is the same as my Aleph-X (stock Grollins). But I did not a direct A-B comparison.

Hi,

I can only compare my Aleph 5 clone to my Aleph-X.
In short:
bass is faster, better controlled
mids are less romantic/bloomy
highs are more precise and offer a bit more information.

The nice thing is that this doesn´t make the Aleph a bad amp. I still enjoy listening to it but, I like the X more.

As a project the X was/is a lot more difficult and it is still not really finished (dc-servo is on it`s way......)
