Power Conditioning Help Please?

Are you using several dedicated circuits with high end AC outlets?
That's the first place to begin, asuming you don't rent.

Thank you for responding. No...no dedicated circuits or high-end outlets. Not sure if dedicating the circuits is practical due to limited outlets...required for non-audio devices. Have seen ads for outlets, but didn't understand if they'd make a difference or not.

Presently, I have most of my stuff plugged into a cheap Monster Cable conditioner.

I have installed dedicated circuits. Each has its own new outlet. Fortunately I don't have to use anything more than a simple surge protector, no complicated filtering etc. My power is clean. They don't turn a system you are disatisfied with into something else.

Your response brings about a question. How does one know if his power is clean or otherwise?
