Without knowing your budget here are a few suggestions from low to high-
Peachtree Nova 2 125, 150 and 300 The Nova 2 is much improved from the older peachtree gear.
Parasound 200 Classic Int.
Cary Audio SL 300.2D My son just bought one. It sounds fabulous. It's list price is $6K but you can pick them up for $3500 or so. 450 wpc at 4 ohm, does streaming and has a very good DAC that would be comparable to a DAC in the $1200-1500 range. It is very music, detailed and throws a huge soundstage. It is very dynamic.
Primare Prisma I-25 or I-35
Marantz PM KI Ruby- I heard this last month and it is a beautiful sounding Int. It has great tone and some of the best piano that I have heard. The Marantz Model 30 sounds muddy in comparison.
Luxman AX505uxii. When I decide to ditch my Pass amp and BAT preamp for an Int, I will go with a luxman AX507 or 509. These are very detailed, clear and refined with excellent punch and dynamics.
