Voltage fluctuations

Perhaps installing a dedicated sub-panel with dedicated outlets to support your music and/or A/V system would solve the problem. I'm no electrician, but I hired one and did just that. No more pulsating lights when the volume is turned up loud. Plus it sounds much better. Best of luck.

Thank you all for your responses. I am currently using a power conditioner (unfortunately not a regenerator) which is how I know that the voltage is not stable. Hopefully the spikes are not drastic. I'll sleep a little better knowing (instead of hoping) that 110V should be enough to run my system safely. Thanks again!

By the way, Waveman, was it terribly expensive to get the dedicated outlets?

I use an APC regenerator - it works fine - it makes a click when the AC goes on as it adjusts the voltage to keep it within target range.
