Rogue RP-1 slight hum

Good morning all,

I just bought a new Rogue RP-1 pre-amp. I love it! it was like opening up warm taps on a faucet. 

Small issue I have is that when at idle, no music playing, I get a slight high frequency  hum and hiss. I swapped out the stock JJ tubes, and it helped but just a bit. Also shut off the main display, no change. Swapped out the power cable for a nice one from AQ, no change. I've e-mailed Rogue this morning, to see if I'm missing something. 

Any suggestions would be appreciated. 

Thank you

Rogue is quite responsive, what do they say?

Maybe the ICs are running alongside a power cable and picking up interference?

Its not the tubes! Lets be clear this is nothing more than having a more sensitive system, and its going to show any anomalies. Make sure power cords and IC's are away from each other. Does the system have a bunch of HT or video stuff involved as well? I find mixing the two can cause lots of problems with noise and hum.
