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 had a MC452 connected to Magnepan 3.7s then 20.7s.  It had a bias issue so my dealer loaned me a pair of 601’s which I compaired to a Sanders Magtech, the Magtech totally outperformed the 452 and the 601s, much deeper and solid base, like adding a sub to a system.  A few years later I borrorwed a 4b3 and that out performed the Magtech by a larger margin than the Sanders over the 452/601s.  I wanted a little more punch than the 4b3 so thats been upgraded to a 14b3 which is a beast.  The only amps I would consider over the 14b3 would be a Burmester 911 or a D’agostino Momentum and they would have to prove themselves on my system before I would commit.  The 14b3 specs (which is not everything) are better than all the amps listed here.  Someone on this thread said Bryston is not high end, not sure where that thought came from but IMHO Bryston rocks and can handle any speaker out there.
