My roommate bought an Audio-Technica AT-LP60 turntable. The turntable has both phono out and line out. My amplifier doesn't have a phono input, so I must use the pre-amp in the turntable. I'm not really a huge fan of the sound. I've seen some really cheap pre-amps on amazon.com for around $20. Is it worth it to buy one, or would it not really improve my sound much? I'm almost embarrassed to put the links up.
Unfortunately, my budget is pretty low, under $100, because I'm also in the market for a new receiver, for which my budget is around $300. Should I just buy a receiver with a phono input, or would an external pre-amp, however cheap, sound better?
