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.

Lak, yes, my personal opinion that cables should be considered as components. Cables synergy with gear is very important. 
I wish I would realized it much sooner in my journey. I sold/traded quite a few great amplifiers because of the poorly matched cables. Btw the pass int-250 sounds terrific at low volumes, probably the class A bias at lower volumes plays some part. I would strongly consider class A pass separates (pass 100.8 or even better 160.8) , but they generate a lot of heat.

denon1:  Keep us informed of the progress of your search.  Perhaps you could take a step (funds permitting of course) up to an "uber integrated" the likes of

Ypsilon, Absolare, Vitus (SIA-30), Soulution, Dartzeel, and of course, T&A.

Sorry, chiming in late.  It's your speakers, not your amp.  Speakers are where the main difference in sound occurs, not at the amp.  I'm not saying that all amps sound the same, but the effects you specifically mention (explosiveness and drum kicks) can more effectively be managed by a change in speakers.  All the integrated amps you mentioned your amp as "overall better" than are top notch amps.

But maybe it's not the speakers.  Maybe it's your room.  Any speaker is limited by speaker placement and room interaction.  I would consider getting a good room analysis before spending any additional money on gear.  You can do it yourself, but IMO a good room wizard will work magic (sorry for the pun).
