Voltage fluctuations

I don't think that a constant 110v would be too problematic. The more serious concern is the fluctuation. You don't need to have a catastrophic lighting strike. Even little surges of power are very damaging to electronics over time. You may want to consider a voltage stabilizer. Here's a link you can follow for Monsters', although I am sure you could find others if you prefer.

A power conditioner cannot adjust your voltage higher than what's coming out of the wall socket, unless it is a regenerator. Those are designed to generate the proper voltage and eliminate fluctuation, IE: (http://stereophile.com/powerlineaccessories/181/) 110v won't cause any actual damage to you system, but it's sonics may suffer slightly from the lack. With two large tubed monoblocks, a 255wpc woofer amp and tubed output section in my CDP, I've got a bit of current draw. I turn off the air conditioner and don't run any appliances while listening to the system. That keeps my listening room's voltage at a steady 120.

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.
