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 home demoed both the Diablo 120 and 300 before I purchased the 300.
The Diablo 120 imho at medium to low volumes sounded as good if not better than the 300. But as a value taking price versus power the 300 won me over.
The Diablo 120 has a special promotion now which makes it a good deal. 
IMO these integrateds are easily the best solid states on the market. The Live and detailed presentation is the best I have ever heard.
 That being said I sold the Diablo and went to a Vac 200iq tube amp. Being an old guitar player I just prefer tube amps in general.....that je ne sais quoi...factor.
My Diablo 300 was barebones as I only use digital streaming from a LUMIN U1 to a Chord Dave Dac via AES/ebu.....then to the Diablo. It worked splendidly.
Inna ......in my present system I have the LUMIN U1 to the Chord Dave to a Vac Renaissance Mk5 Preamp to a Vac 200iq amp to a pair of Magico S3MK2 speakers.
I have absolutely no interest in analog and I prefer the flexibility of choosing my own Dac. For the record I got a very noticeable SQ increase when I went with the LUMIN U1 streamer over my Mcbook Pro via USB to the Chord Dave.
