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.
