Jaybo is right, "they are not fussy, so any quality integrated in your range will do just fine". Don't spend more than $350. A used integrated like Onkyo 9555 will be my first choice. You'll probably get very close result weather you spend $350 or $500.
Spica TC-50 and amp advice
I was recently given a pair of Spica TC-50 speakers and am not sure which direction I should go regarding an amplifier. In the meantime, a friend is letting me borrow his Baldwin 6L6 tube amp. I'll also be running a PS Audio IV preamp, California Audio Labs CL-10 cd player and a Rega turntable. I'm newly divorced and finally get to enjoy my equipment. My new living room is approximately 13'x14', and I have thousands of live shows I've collected through the years and want to be able to get the best out of what I'm working with. I've budgeted $500 for an amp and don't know which route to go. Any advice or suggestions is greatly appreciated.
