Rmb1585 floor noise?

[prk504]

Does anyone experience a slight him from the tweeters when using the rmb1585?

I have a slight hum with no audio coming through..I've tried disconnecting all the interconnects and the trigger. The amp is plugged into a Tripp Lite Lc1200 and I've tried plugging it in directly to the wall. no luck.

The hum / buzz is only audible with my ears to the tweeters. I have 804 d3 towers...I called magnolia at best buy and they said that their showroom rmb1585 powering their 804d3 towers has a hum too.

Is this normal?

I had RMB-1075 a long time ago and i remember to have this hum on my B&W 804s at the time. After that i bought Mcintosh MC275 tube and used a lot and no hum. Few months i returned to Rotel processor and hooked Marantz 7055 5 channel power and i got this same hum, very low, but i hear with my Sonus Faber Olympica II. (now i use dedicated power electric). The power is producing this hum. I think its a not so good isolate power amplifier (but good sound quality).
