  I wonder what's the total capacitance of BHA? It must be comparable to something like the BP17 or BP26?

Looks like 46,200 uF total for the amplifier rails in the newer design.  12 caps 3,300 uF caps on the main amp board and two on the power supply board.  For the production release, Bryston has chosen to locate the caps around each amp module for lower noise rejection -- a good design practice.

An even earlier prototype with designer Stuart Taylor.

Thanks for this. Where did you find these specs?
 
Bryston does power supplies and internal noise reduction very well.

Not to speak for WilCox but schematics are on page 10 of the manual.

I actually preferred the BHA-1 as a pre-amp over my Bryston BP25P with the MPS-1 power supply.

That's really saying a lot. I tried BHA once, driving my 4Bsquared and VA Mozarts. Not good. But that's compared to my B100 (BP16 preamp section). Oh well,...

Ahhh...should have known...the manual. Thanks. Always a neglected resource in my household...unless something goes wrong of course.

Interesting…in my case the with the 4BSST driving my Dynaudio Special 25s  the BHA-1 added a lot more depth and width to the sound stage with an even smoother, airier and more detailed  top end over the BP25P.

Hmm...very interesting indeed. Reading this makes me want to get balanced cables and connect the BHA-1 to my Parasound A21 for a direct comparison against my Conrad Johnson ET3 preamp.

I'm going single-ended to my speakers. Could be a reason for difference in our experiences.

So now the question is how would the BHA-1 compare to the BP26 as a preamp.

Then again, as I read through older posts on Audiocircle, James from Bryston (around 2011-2012 timeframe) confirmed the BP6, 16 & 26 all share the same gain stages and the differences are not 'performance' based but rather 'application' based, ie. Connectivity/features/remote, etc.

So far we have CanadianMaestro preferring the B100 (BP16 based) over the BHA-1 and Rob80b preferring the BHA-1 over the BP25.

I guess this all makes sense and both would be correct (somewhat by triangulation) if the BP26 is superior to the BP25. Am I making sense?

Audio perception is never linear, like "if A>B, and B>C, then A>C". As JT said, it's based on "application", not performance.
 
For 2-ch audio, I wouldn't use BHA-1 as a stand-alone preamp driving floor speakers or feeding a poweramp. Just me, I guess.

I agree regarding the audio perception, and let's face it, the subjectivity factor is quite high in audio.
This is especially true when 2 respected members such as yourself and Rob80b have literally opposing views/experiences with the BHA-1 driving power amps.

Flattery will get you everywhere....
 
Probably our speakers respond to BHA differently.
Vive la difference.

 
(Rob loves his HD700, I hated it when I auditioned it. Too bright to my ears.

The world would be a very boring place if we all liked the same things.. as I drink my Guinness.
