AudioPrism Quiet Lines

I agree with above, make modest improvement without hurting sound. Blue Circle makes more expensive similar product "Noise Hound" that works even better......I have two Noise Hounds and set of 8 Quiet Lines placed at key outlets as noted in product directions.

It's the CHEAPEST way to get slightly better, cleaner sound. I have only ONE of these plugged in, and I can hear it's contribution.

The lights in my wife's laundry room used to blink & flutter when the washing machine was going. One quiet line on the same outlet as the machine brought it down to a barely noticeable flutter. They do work. I also put one on the fridge (obvious place) and directly on the AC recipticle where the amp plugs in. Definite improvement on the amp, primarily in the midrange textures and dark backgrounds in the highs without any compression of dynamics.

Enjoy,

Yes they work. I was a non-beleiver until a dealer loaned me their Noise Sniffer and some filters last weekend. I was surprised to find that some of my components generated noise. The worst culprits in the house were the light dimmers on the dining room and breakfast room lights which the Quiet line filters were unable to totally remove (thankfully these lights are not normally on when I listen. My receptacles in the stereo room are on a single breaker, but the noise from the dimmer switches went all over the house.
I also had a Monster AV power bar which worked very well to remove the noise. Once I identified with the Sniffer where the filters shoud be used, I was able to hear an improvement in smoothness and a "blacker" background with even one filter in the circuit. I ended up using the Monster plus 4 filters.
