I love my new M60s - have had them for about 6 weeks, however, I have noticed a humming noise between songs when I turn my M60s up to moderately high sound levels - about 2/5 and higher on volume knob. I am running a NADC320BEE with a 13yr.old Sony CDP670. Cabling is Ultralink 14g and Ultralink cables linking the CDP to the NAD. Any suggestions as to how to clean this up and what causes the noise? Would better cable such as the Axiom 12g or a newer CDP help? There seems to be a bit of a dead spot on the back of the CDP...if I wiggle the left connector I lose the sound in the one speaker. I am not the most technical guy so any suggestions would be greatly appreciated.
Thanks,
Curtis
