Socrates:
If the TV and other electric stuff at home are disturbing, you might just for kicks try some ferrite chokes in the ofending appliance power cord.
Also if you feel safe doing more evolved DIY look for some directions on capacitor filters that could be used to improve this situation.
I also have tweaked monster HTS 2000, changed power cord, played with cone/spikes now on bearings , internally have dampened, stiffened circuit boards....next is wire changing and resoldering as Sean suggests
All previous mentioned tweaks have improved performance

Luis
