    Well, I will give him more time. Yes, everything is grounded. The following is the PM I sent to Kevin. "I tried different rca's, speaker cables, power cables, speakers, power outlets including the power conditioner".

    I replied to your PM. Unfortunately ground loop issues are sometimes very difficult to pinpoint. I apologize for longer response time, as I have been covering for a peer at work which involves working less than ideal shifts. Also give me a call this evening if you like.

    Ground loops and other electronic noise can be a real PITA. Have had single components switch outs that have revealed issues elsewhere in my system and home wiring.

    I remember someone recently had an issue with a light dimmer switch causing noise on his phono stage. Maybe it's something like this?

    Id check all the screws on and in the case for tightness. Shipping vibration/ guerillas can cause all kinds of issues
