I got a USB turntable several years ago as a gift. The A/D converter to the USB interface sucks boulders but the TT has a built-in preamp so it's a simple matter of running a stereo cable to the sound card line input and sounds 100% better. If your TT lacks a preamp you can get one for $17 at Radio Shack. The TT I got is DC motor belt drive and has solid speed so there are no wow/flutter issues. My kid broke the damn needle though and I haven't replaced it yet. We've got about 150-200 albums too but sadly they have not been taken care of very well and most were bought used and in not so great shape when we got em. Somewhere in life travels I lost two cleaning kits I had. A new kit costs more than a new stylus.
