Upgrading form Pass integrated amplifier to a better one

Hello,

Currently I have a PASS INT-250 integrated amplifier . The Pass INT-250 is a very good integrated (in my system it was overall better than Plinius Hiato, Gamut D150se, Mark Levinson 535, Vitus RI-100,  Accuphase E-470 and some others) but I can't get rid of the feeling that I miss some explosiveness (drum kicks for example) and micro details.

I know that its not the speakers. The new Sonus faber tradition I have are much more open, dynamic and airy than previous Guarneri Evos, Elipasas SE and Amati Anniversarious I used to own. And before buying them I auditioned the Serafinos with Audio Research separates and it was the amazing combo. But I really prefer not to go the separates road ( ICs, power cords and space contribute to financial constrains also) and even so I like the combo of Pass and Serafinos overall but from time to time looking for some better integrated on the market.

Currently I presented with a good opportunity to buy latest Gryphon Diablo 300 integrated or latest just released Accuphase E-650.  No possiblilty to demo them, so I am asking here on the forum if anybody can comment if Gryphon Diablo 300 or Accuphase E-650 will be better integrated than Pass INT250 overall and especially in terms of dynamics, micro details and harmonics.

Any advise and opinion would be very appreciated.

My system: Esoteric K-05x, Pass INT-250, Sonus Faber Serafinos, all cabling are the Shunyata Sigmas.

Room is 12" wide by 17" long. Listen mostly acoustic jazz and chamber classical on low to moderate levels.


Thank you.

Greginnh, so you are saying that E-600 is more refined than E-470?, what else, more 3d, more texture, micro details, how its bass?  I never buy retail and currently have a pretty good deal on coming E-650 since its supposed to be better according to a specs. But again no possibility to audition.

Thanks again.

Better in all aspects and nothing missing in the bass department. It's almost impossible to find an Accuphase dealer who has the item as a demo, available for in-home trial.

Greginnh, thank you for the valuable info. I may get back at considering Accupase E-650, especially since the Accuphase dealer is offering pretty good deal. This may explain the popularity of the Accuphase, because of the class A.

Spending $16k on an amp without auditioning it and having no idea how exactly it would sound in your system and whether or not you would like it? Think about it, it's nonsense. Gryphon Diablo will easily drive your speakers and most other speakers. So what ? You might not like what you hear just as you don't quite like the Pass.
