White Noise

Can anyone help me eliminate the white noise coming through my front speakers when I use HT bypass mode. I have a Marantz SR 5011 AV receiver running my center and rears speakers. The Marantz is connected to my Jeff Rowland Corus preamp because I want my Jeff Rowland amp to drive my front speakers when watching movies/TV. When I'm listening to music through my 2-channel everything is dead silent. When I'm watching movies or TV and employ the HT bypass I hear a significant amount of white noise coming through my front speakers. Can anyone tell me why and how to eliminate it?

auxinput,

Thanks so much for the detailed response. It's definitely a hiss and not a buzz. The Corus and Marantz are plugged into the same Torus power conditioner. I'm using Audioquest Golden Gate interconnect cable(will getting better cable help). I use Wireworld Silver Eclipse 7 for my 2-channel.

I don't think getting a better cable will help because the cable will still transmit whatever is in the signal (including the hiss).

auxinput,

Thanks, I'll try your work around suggestion tomorrow. I reached out to Rowland to see what they suggest. They're very helpful and should be able to give me some advice.

I solved the white noise by replacing the stock power cord with a 6' Audioquest NRG-2 power cord. The power cord reduced the noise by 95%.
