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.

Ypsilon Phaethon integrated is $25k retail. I have not heard it, but by all accounts it is great. Gryphon Diablo 300 should be able to drive very well many different speakers.

Just sold the VAC 160i SE and acquired the Pass INT-250.

Its a better fit for my room and with my Harbeth 40.2

Better bass, more transparency, more detailed.

Dont hear any drawbacks as the VAC was neutral for tubes and this PASS is not forward

Perhaps the gryphon or ypsilon integrated is better but at twice the cost this is certainly a relative bargain

Some update, the Gryphon continues to sound better. I have around 150 hours on it and I think its fully opened up and sound outstanding. For sure in anther league from Pass INT-250. Now, esoteric will increase its retail pricing across the board worldwide by 10-15% on 12/24. This and great offer from my dealer pushed me to do a long wanted upgrade from esoteric k-05x to esoteric k-01x. This is the final step to achieving what I want and I am done. Once hi end streamers become less expensive I will look for something like Aurender N10 in a couple of years.

Happy holidays and outstanding 2018 to all.
