Default Best Pass poweramp?

I'm considering building a power amp, and have heared a lot of good thing about Mr. Pass constructions.

So, witch one to choose, and have any one done some improvment to the original design?

It depends on what you like and what your setup is. You can change them to suit your taste. What do you want to drive with the amp and how loud?
Yes, the amps sound very good.

Question What is the list in order of Efficiency?

I'd be interested to know what the most efficient Pass Power amp is... I've only got a limited current capacity in my tiny apartment, and running a 5.1 surround system with all Aleph-X amps might be too much for it to handle.
Can anyone shed any light on which are Nelson's most efficient power amps?

the most efficient would certainly be the X series (not the AX, the X)
but they're not available for DIY

5 Aleph amps in a small apartment would generate WAY too
much heat

Yep, that's about what I expected. The Gainclone sounds like a viable alternative. But being the devoted Pass fanatic, I'm considering tackling a design based upon those being discussed in the Monolithic supersymmetry thread. There was one, here (second one down the page):

Monolithic SuperSymmetry with Current Feedback

or at the bottom of the page here:

Monolithic SuperSymmetry with Current Feedback

That might just work for my purposes.

An Aleph3 (200 watt I believe) might still be acceptable (especially in winter).

I always wondered, isn't there some way you could use the excessive heat to produce electricity (or do something usefull, apart from frying eggs)??

Aleph 3 has the highest bias. The 5 is the most efficient.
