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.

Hello, I got the Gryphon Diablo 300. It was delivered to me by freight on a pallet. After 5 hours of burning (it was totally brand new), this is my observation in compare to Pass INT-250. First obvious difference the low and mid bass on a different level - deeper tighter and more detailed. Second; the Gryphon's dynamic agility is best I heard at my house. The drum kicks, piano notes appears all of a sudden with such clarity, impact and focus - much closer to live performance than pass. The overall presentation is more neutral but still very musical and of cause micro details - on a new Bill Charlap disk I clearly hear him pushing pedals on his piano. I did not hear it with pass that clear. The only area for now were pass is may be better is soundstage of the pass is larger up front, but may be its just because the Gryphon is so new. At the same time the Gryphon's soundstage is deeper - again closer to what I hear attending to real live concerts. So to me in my system (even so Pass is terrific performer) Gryphon Diablo bring me another step closer to live performance with its low/mid bass,dynamic swings and micro details. And another very important aspect - no listening fatigue at all - outstanding for a brand new unit. My search for a perfect integrated is over.

My big thank you to Mike from Suncoast audio for his outstanding service and making it it possible to happen.

@denon1, Thanks for the update. Please let us know after continued hours of break-in if there are any aditional improvements.
Until then, enjoy the music!
Great. Yeah, give it couple of hundred hours to fully burn in. When you recover from your expenses you might consider experimenting with cables. This is a very high performance level, and everything matters even more.
Tube integrateds aside, there are only two that I would consider for myself if I could afford them - Diablo 300 and Ypsilon Phaethon hybrid. Your Diablo should work just fine even if you replace the speakers at some point.
The Rogers EHF 200 (or the 100) is a great sounding integrated amp with loads of dynamic slam although sort of pricey…I've heard 'em, know people who have 'em, and if "tube like" is a thing you want out of an amp, get a tube amp. Lifetime warranty for those.
