Question about Sharper Image SR277 Speaker
An annoying hum overrides the music when speakers are turned on. Please advise
This may indicate a ground loop problem. Try to have the power supply for the speakers and the music source plugged into the same outlet. Try another connecting cable if possible.
It's also possible the power supply for the speakers isn't working correctly. There are filter capacitors inside whose job is to smooth out the voltage that would make such hum. They may have bad connections to the circuit board inside (a common problem) or may have gone bad. You can check for and possibly repair these problems yourself if you've done any electronic soldering, or see if a TV shop in your area would give an estimate.

I also had a severe hum or buzz that was NOT a ground fault loop issue or any other such problem.
Hummed to the point that reading in the family room was annoying !
I took my amp to a Very Qualified shop and the technician simply insulated the transformer 40.00 usd
