Does excess voltage cause hum?

My power conditioner frequently reads between 120-124 Volts. I hear a slight hum from my speakers. Is this the most likely cause?

Cyberlink Platinum Coax, H.T. Truthlink analogue, H.T. Pro-11 AC power cord, Synergy Rack system, Toshiba TW40F80 widescreen PTV.15amp ac outlet, and one 20 amp dedicated outlet. The Panasonic DVD player is temporary. I will be getting either the Sony DVP900ES DVD/SACD, or the Pioneer DV-37. Perhaps their is a weak point here that I have overlooked?
