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.
