budget power conditioner

I've had great results with a PS Audio Quintet. I live in an old apartment with knob and tube wiring and no ground. I have two restaurants a floor below me and refrigeration units a floor above. You couldn't ask for a worse situation in this hobby. The Quintet completely eliminated the noise. The Duet has the same design as the Quintet, but with four receptacles rather than ten. There are better power conditioners, but you'll have to spend a lot more than $300 to get them.

APC. Perhaps the H10. Surge protection and voltage regulation. I use the H15 in my HT.

There is a AM Stealth in classified 345.00 6 outlets ,very good unit,works well in my system

PS Audio Duet fits your needs...works well too.
