What kind of amp?

Hi. I would welcome opinions and suggestions for an integrated amp (ss or tube)(new or used) that would go with my system. I am venturing into the great new world of hi-fi and am tin the process of upgrading -- I am a bit overwhelmed by choices. I am looking for a good, solid all-arounder -- jazz, classical, latin, pop/rock, and thought this would be great place to get some advice. I have about $2500 or so to spend.

System now --

Heart CD-6000
Harbeth compact es&'s
Planar 3 with rega arm
Audioquest type 4 cables
Old creek 4140 s2 amp.

Thanks in advance for your help.
