Help I got a big time Hum in my system


I just put my HT system together. It consists of Aerial fronts Aerial rears and Aerial center and Paradigm 15 sub...power is Classe ca300 for the fronts Parasound 2203a( 3 channel) for the rears and center.The pre/pro is an Aragon
Soundstage....Cables are mostly Straightwire.
With that aside I am getting a loud hum out of all channels in all modes....it is always present even when the processor is off. It will get louder when I turn the processor up to about 60 per cent....but in lower volume settings it seems to bee constant. I do not have any power conditioners in the system at this time.....The outlets are suppose to be dedicated circuits.....When I have just the amps on and take off the interconnects to the processor it stops.....Is this a problem with the way the electrician wired my room......I need help bad Please!!!! Thanks

Be sure to use a star configuration where the power cord of each piece goes to a single source of current. You probably know that but just in case I thought I'd mention it.
Good luck.
