Bellari Hum


I've been noticing that I'm getting a buzz/hum coming from the speakers when using the Bellari VP129 phono preamp. I have the ground wire attached from the turntable to the Bellari, but I'm still getting a hum. I have the Bellari going directly into 2 NAD C272 amps running in bridged mode. Anyone had this problem before, or have any suggestions?

Thanks

I also enjoy the sound. I either didn't notice the hum until last night, or it just started. I may try using a ground adapter that plugs into the wall and has only a single wire coming out for a ground connection. I'll leave the ground wire between the Bellari and turntable, but add another wire between the Bellari and the ground adapter. I'm also going to try moving the Bellari around, because it may be picking up some kind of interference from the amps; I can only move it so far though...I don't have super long interconnects.
I'm noticing that the hum comes and goes. There is no consistentcy here. It may happen for 5 minutes at a time, then I won't hear it for a good hour or so, then it will come back. Very frustrating.
Wow what a coincidence that I googled for this topic and it brought up my old thread, only to find that there have been some recent responses. I am still getting this buzz every now and then. The weird thing is that it's not consistent, and I can't determine what makes it come and go. I may try another power adapater and see what that does. But when listening to classical music that has quiet passages, this buzz can become VERY annoying.
