Depending on how much power you need, Audiomat makes stupifying integrated tube amps for very friendly prices. There's one for sale on audiogon--the Solfege Reference (top of the line). It's integrated so pre-amps can get sold to cover costs. A hard choice to make if you can't listen to one first. I own the Arpege Reference (entry level), and I can't tell you how in love I am with the sound. I did get to audition it as well as a number of others.
Good luck
