setup
Netbook running on batteries to USB power DAC to tube amplifier.
tube amp plugged into AVR
subwoofer and fan plugged into extension which is plugged into same AVR
When i turn on the fan on occasions music stops, i have to restart itunes to fix it. Any ideas whats going on, i reckon theres "surge" of electricity somewhere in my systems, but my netbook runs on batteries. Is it possible that theres a surge of electricity from the amp going to the dac via the RCA ?
