Rogue RP-1 slight hum

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

Nearby router?

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.

Thank you all for the thoughts and suggestions. 

Rogue was awesome! Everything I heard was true about their customer service and follow up. 

Issue is the sensitive nature of the Klipsch. I made sure all IC's are away as much as possible from power. There's no router in my room, or on the same floor as my listening room, no video either. 

I am impressed with the sound I've achieved with my system right now, I believe I have the right combo of pre and power to meet all my needs. However I do believe some light is shining on my speakers and their shortcomings. 

Rogue service is great.

I was having a bit of the same here, tried plugging everything into an outlet strip on an extension cord and trying different circuits ect. 

yes those high efficiency speakers will bring all that out.

Rogue service is the best.
