ACA vs Aleph (or other Pass Amp)?

[mpeg2]

I recently completed an ACA build - really love the sound of the amp. My room is not too large (about 15' x 18') - and I'm using Klipsch Cornwall speakers. There seems to be sufficient power to spare for the majority of what I'm listening to.

Would there be any compelling reason to contemplate building a different design for use here (besides the obvious one of the enjoyment of building itself)?? Would there be a significant improvement in sound?

NP says all his amps sound different from one another, and he has written (somewhere),
describing the relative sound of several of them.

Yes, thanks. Many people build amplifiers (or other audio gear) because they want to,
not necessarily because they need them. Follow your heart.

I've always wanted a pair of Klipsch, and someone recently said that the M2 was good match for such speakers. Seems rational to me...

Well, certainly the M2 side 😉

Thanks all - lots of reading & research to do. For me, enjoyment is a major reason for doing something - both the build & the use. Sometimes, the build itself is sufficient rationale - but here, the use would be an added bonus.

I'm about to retire - this is one more thing to add to the new "todo pile".

Here`s my experience.





I`ve build the ACA a SymAsym and some FW. Amps: Aleph J, F5.




I compared the J and the ACA. The way they sound wasn`t a really big difference (not significant in my ears).


But the ACA had not enough drive for my Speakers (only 89-90dB at 8Ohm) mostly noticeable in Bass at higher volumes.


My ACA had a regulated PSU. Done like in -The ZEN variations Part 3-
because i had to lower my Rail Voltage.
So maybe this could be a upgrade for your ACA.


My Conclusion was: If the ACA had enough power for the listening, there is no need for another amp.
In the end i`ve sold the ACA & the SymAsym.

but aleph is hotter than anyone 😀

Danger Mouse: Thanks for the data point. I'm not running out of power with the ACA (small room, efficient speakers). Maybe I'll look into one of the other designs (besides the Aleph J) - I do enjoy building these.
