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....

Nyev,

You read my mind! I’ve been searching the web every few months for a quality, experienced review of the MC462 as I need an amp for my relatively new Martin Logan 15a’s. I even went so far as to send Mac an e-mail requesting they send a unit to my favorite reviewer, Christiaan Punter at Hifi-Advice... Who btw has an incredible review on the Bryson’s you might want to read for reference:

Look forward to your perspective on the Bryston vs Mac!

Nyev,
Missed your later post about not being able to get your hands on the 462. Well...alas, my search continues for a 462 review. There is one that Mac has attached as a marketing tag in their MC462 marketing from a Norwegian reviewer, though it is so bad, it sounds like the reviewer just read the marketing hype on the 462’s increased dynamic range and usual power, and then added a few more words to make it their own. Really, that bad, unless a whole lot is lost in google translation to English.

I’m still keenly interested in your comparison: 4B3 v MC452 as HiFi-Advice sent me a private email raving about the Bryston’s paired with my Martin Logans, however he admitted without hearing the Macs, that’s just a straight recommendation.

Nyve,

Thank you for the review. I said it earlier, the Bryston cubed series and Mac MC462 (452) are two of the amps in my list of 6 I’ve narrowed it down to. Thus it’s like I have a personal reviewer, lol.

Sounds like that recommendation I got on the Brystons was dead on. Keenly interested if you still feel the same after hearing the mc462.

Nyve,

Understood on the different setups. It doesn’t matter as much as I’m looking at the Bryston 14b3. So if the 4b3 was nearly or in some areas better than the 452, it can be guaranteed that the 14b3 will be the clear winner as it has been reviewed as far better than the 3b or 4b combined. I doubt 462 is that much better than its previous model.

Nyve,

Boooo....no 462 review!?!?

; )

I’m getting the Bryston 14b3.. Besides, went to the Mac house in Manhattan, and they were rude. Now I need to figure out a preamp for uae with my ML 15a’s. Gonna keep using my Cambridge 851n as the preamp in the interim.

Best of luck and great listening with the Diablo Nyve! I read a review on it thanks to you. Truly unique design. Like how the first 10W is class A out of it.
