Monk is correct. Even the newer BC amp that is a hybrid with 120 wpc stereo amp is very nice. You can get some nice Amperex 6DJ8 Bugle Boys for cheap and have a great sound if you don't want to go with the older models. You can also get a old Counterpoint SA-220 and have it modified with the 6SN7/VT-231 tubes that has 220 wpc. Also the Rogue 120 mono blocks are good starter amps.
Happy Listening.
