I have a pair of PS audio outlets in the back on there own 20 amp circuit. The preamp is plugged into the Monster Power preamp outlet. Its powercord is a Nordost Shiva. My McIntosh amp has a slight audible buzz if you get right on top of it. (sounds like a transformer buzz to me). Wondering if it is throwing some noise out and the preamp is picking it up. Used the headphones jack and heard no noise through it. Not sure what that means though.
Thanks
