Hey, if you can bear to turn off your receiver (an amplifier itself), you can just as well turn off your subwoofer. Don't sweat it - the potential sonic gains to be made from leaving a SS amp always-on probably aren't detectable in a sub anyway (and that's not even considering that most recent subs use lower-fidelity 'Class-D'-type internal amps to begin with). Or, leave your receiver on. I'd just eliminate the symptom and not lose any sleep wondering about the cause...
Another Issue with Hum.....Advice Needed
I know this has been beaten to death, but I recently introduced hum to my system, and am having a hard time figuring out how to resolve it.
I recently added to my sysyem an active subwoofer that is being fed a speaker level signal from my Receiver's front channel speaker outputs. When the receiver and subwoofer are both turned on, there is no hum. When I turn off all components except my subwoofer and 2 channel amp (I like to leave all amps on), a fairly loud hum can be heard from the subwoofer. The entire system was dead quiet before the sub was introduced to the system. This is not an issue when listening to music, but it is annoying and worrisome when the system is not in use (standby).
I should add that all components (Receiver, DVD player, CD Transport, DAC, etc. are all plugged into a VansEvers PLC and I have decent aftermarket power cords on most components, including the new sub. I suspect some sort of ground loop, but I have no idea how to resolve this. Any ideas would be apprciated.
