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.

One of the most interesting thread I have come across in recent years.
I have been considering replacing my ARC tube separates with a top tier SS integrated for several years now. I have a pair of Verity Audio Parsifal Encore with 89db effeciency that I like very much. 

Would like to pair a good SS integrated with those and reading through this thread it would appear that a Vitus SIA-025 or Gryphon Diablo 120 would likely be a good match. However, like you guys in the US there is no possibility to audition either one in Canada as there are no dealers or distributor.

It would replace an ARC REF3 LE and a pair of Classic 120 mono’s that we’re both modded by GNSC a few years ago. They produce 110w/ch with satisfying loudness level in my 15’x 23’ room. Would love to hear a Vitus or Diablo 120 in my room with the Parsifal. I feel that a Diablo 300 would be overkill.

This would be my very last amp. I would however likely keep my REF Phono2 and Weiss DAC.
Anyway as someone pointed out somewhere above, very good thread indeed.

If it may be your last amp why not make it the great first ? Diablo 300 would be just right and would bring more out of your speakers.
Listen to youtube, same Gryphon speakers with Diablo 120 and Diablo 300, you can hear the difference - much more powerful and easy going sound.

Agree with Inna, the Gryphon diablo 300 not only more powerful but also more refined than diablo 120, plus you want it to be your last amplifier.

Granted that the diablo 300 is more powerful but other than you who else says the 300 is more refined than the 120?  Have you listened to the 120 in your system to make your conclusions?
Yes the diablo should have better bass and possibly play louder but with the right speaker tell me why the 300 would be more refined?

Bob, I did not listen the 120 but I called gryphon myself and they told me that diablo 300 has class A  dual mono preamplifier stage that is taken from their refference preamplifier. This contributes to more deatails and better instrument placements in the sound reproduction 
The 120 does not have it.
