I hooked up the Marantz 7005 and Outlaw 7700 amp directly to the outlet. I turned on just the amp and there is NO noise coming from the speaker. I turned on the 7005 (no cables other than the XLR cables are connected to the 7005) and i get a VERY slight buzz coming from the speaker. From 5 feet away, it cannot be heard.

Now getting ready to connect all cables and plug everything into the new Tripp Lite....
