I recently saw one of these amps for sale, and the listing included this note: "...this amp does have the low-level hum/buzz that this model is known to often have. I understand Cary Audio has a tweak that can eliminate it. There is also some discussion on audiophile boards on addressing it. Some folks are moderately bothered by it. Some aren't at all. It also seems most sellers don't think enough of the noise to even mention it." I don't know any further details, but apparently the issue you're having is not unusual with this amp.
