Bryston 4B3 vs Mac MC462 vs Pass Labs X250.8, OR... GRYPHON Diablo 300?


Hi,
Over the next few weeks I am organizing in-home demo of  three pre/power amps for my B&W 803D2's, and will purchase whichever sounds best.  I will be testing the following gear, which is based on what's available where live:
-Bryston B173 / 4B3-McIntosh C47 / MC462
-Pass Labs X250.8, if I can get my hands on one (will probably use the C47 pre-amp to test with this)
The Gryphon Diablo 300 is also a candidate.  I've seen some strong comments from others that Gryphon is in another league compared to the others.
My question is, barring what sounds best to me during my auditioning, in general to most people would the Diablo 300 really beat the others in my list?  And, are there any material disadvantages to sound quality considering the Diablo is an integrated vs the other choices?  I don't really care about having separates, but sound is obviously important.
Secondly related to the Gryphon, there is only one Gryphon dealer that is even remotely close to me.  Should that dealer cut ties down the road, or go out of business, does anyone know how I might go about getting service for the Diablo should I require it at some point?  Is that a valid concern?  There are multiple Mac dealers near me so that would not be so much of a concern.

Thanks in advance for any feedback....

I appreciate all the elements you noted with the Gryphon sound. For those very, very finite few who dislike this sound
To me they like slightly "sterile" in your face etched sound that you can detect emitting from the speakers drivers, this is to me is a "house sound"
Bryston’s, I nevertheless found it a bit tiring to listen to for extended periods
You just said it!

Cheers George
nyev OP
Diablo’s "tone" is highly regarded, but keep in mind there are a very, very small number of people who don’t the Gryphon house sound.
Gryphon amps are to closest sound to a big pure Class-A linear amp with an iron fist for bass control, without having to go pure Class-A.
If this is a "house sound" then count me in, as that’s the kind of sound that is big controlled and 3 dimensional and washes over you, that never sounds like it’s emitting from the speakers, it feels like you can get up out of your chair and walk into the sound stage. Some very good tubes can do this but they fall down with hard loads and bass grip.
