Power Conditioners

Not sure if I placed it in the correct topic but here goes. I was just wondering how power conditioners work, as I want to buy one. There are conditioners with only filtered inputs and conditioners with some filtered inputs and some unfiltered. I believe the unfiltered ones are for analogue devices. But why should these go into the unfiltered part? If I buy a power conditioner for example with only filtered inputs, will I not be able to put my class A amp in? Or will it have a negative effect?

They are not snake oil. I had a very slight (but audible) buzz/hum with nothing playing and the volume at a normal level. Put in a Furman 15 and the noise vanished. I don't know what they are talking about with extra wall warts. You plug the Furman in to the wall and everything else you want into it. It even has different outlets for amps, low current, and video. Peace of mind and less noise. And for less than $1K - even less if used.

I was wondering if there are power conditioners that can solve the spikes you hear over the speakers when you switch on or off the lights?

Never have had that problem with or without a conditioner. Only way you'll know is trying one in your environment

A series-mode surge suppressor should take care of that very nicely. In my case, I would hear a thump from the speakers whenever the ceiling fan in the room was turned off.

Zero Surge and Brick Wall offer units that are inexpensive ($250-$300). Audioquest also offers the Niagra 1200 but it's considerably more expensive ($1,000).

@dannad: have you actually tried it or are you just pontificating?
