I've set up a nice little system for my teenager. A modified Trends audio class D amplifier, a pair of Omega Super3r speakers, a velodyne minivee subwoofer, a technics sl5 linear tracking turntable. While she mostly streams from her iPhone, she wants to listen to records. Can anyone recommend a decent low cost mm phono pre? I'd like to spend around $50 new or used, but would spend more if needed. I'm not a DIY guy. Thanks.
