dam that's expensive! try and get it from the US on Ebay or something. there are obviously better and more expensive amps out there than the Grace, but like the HP-1s they were intended for studio use and made to be transparent. im sure there are better sounding combos with the HP-1, but i can feel pretty confident that i am as true to the source as financially possible for now which is what i am after. Also, M. Grace is an HP-1 fan so I am assuming he catered a bit to that can when designing the M901 and M902.
If it's good enough for his ears than i am more than OK with that.
