Jafant Lak, thank you, I will. Not an easy decision. The pass INT-250 is very good. May be anybody will be interested in my experience with the integrated..So far in my system, I had these integrated (mostly playing with Sonus Faber or Vienna Acoustics models):
1. Plinius Hiato - great midrange and bass, highs are hot and digital noise persistent - as result lack of air and micro details.
2. Gamut D150SE - good airy sound silky highs, but lack of bass and poor build for the price.
3. Accuphase E-470. Great build. I guess prestige play part. But nothing special with the sound - overpriced in US.
4. Pass labs INT-60 - great one,
beat all the above but when I had Guarneri Evos, I needed some more power to get that relaxed/effortless feel in the sound.
5. Mark Levinson 585 - balanced smooth sound, but I felt its not a best match with Sonus faber.
6. Viva Solista - very good 845 tube based amp. To my surprise has been a good match with Sonus faber Anniversarios. The tube swapping so drove my crazy and it obviously ran hot. On a higher volumes did not have enough power to get SF sing. But with efficient speakers will be outstanding.
7. Pass labs INT-250 bested all the above. Power, musicality, good details. But I know that my new Sonus faber Serafinos can exhibit even better sound - with more flash out micro details and dynamics.
So my only choice that I like to explore is Gryphon Diablo 300.
Even so I appreciate it, please don't offer your opinion on anything else, since I am only interested in Gryphon. Lack of availability to demo, makes me to ask assistance on the forums. So again please anybody with hands on or any experience with Gryphon Diablo and its sound and reliability please chime in.
Thank you.
