Amp Recommendations for Ohm Walsh 2000 Speakers

Hi - I have (and love) my Ohm Walsh 2000 speakers but there is very little out there (even from the company) on matching with a good amp to really make them sing. I think at the NY audio show, they use a Peachtree amp and I was thinking maybe the Peachtree 300 (300 watts/ch) may be good. Or I could even go with a used McIntosh tube integrated amp. My budget is around $2500 to $3,000 for the amp. I do like to listen loud (rock, jazz). I'm currently using an old Hafler P500 (250 watts) but I'd like to upgrade and improve my amp. I have a Vincent hybrid tube preamp. So I could either keep the Vincent and go with dedicated amp, or do an integrated amp. 

So any experience with either tube, hybrid or solid state amps or integrated amps would be appreciated to make these Ohm Walsh 2000s really shine!  Thank you!
