Yah that definitely doesn't make any sense. What I also don't understand is I've read that for that short a distance XLR shouldn't make a difference over RCA anyway. It's usually only what a 1.5-3' cable?? Maybe as DD pointed out because of it's higher then normal SNR and gain but I didn't have anything connected and my speakers sensitivity are only 91-92db. Maybe I missed it but does Jlpowell have a hum with just his speakers connected?

If it's any consolation to you all I do get a slight humm even connected to my Denon 3313.

Yeah, I think the biggest issue is the sensitivity of our speakers. Even with the XLR cables I still have an audible hiss from my tweeters. But it is only audible from a couple feet away, so won't be a problem from my listening position.

Cheers!

Ok that's what I was wondering. I guess DD is right and your speakers efficiency combined with the Sherbourn's high SNR makes it easier to hear. Mine didn't do it when I had my pioneer receiver hooked up. Did any techs from Emotiva tell you to ground from the pre/pro to amp or from the amp to the outlet?
