Power Conditioners

I Bought a CHANG LIGHTSPEED 9600.
I did my Research and Tried several others out there.
Chang is Competitively Priced, made the Biggest Difference, and Very Well Built Product! Also, you need to consider upgrading Power Cords, if you haven't already.
I have Definitely Heard a Difference in MY system since its Purchase. Through Filtering (for EMI and RFI), GOOD Line Conditioners DUE Lower the Noise Floor and allow your system to go Another Level Up. And With a Lower Noise Floor (Grundge), you WILL Hear More Detail and a Blacker Background. I Recommend Staying AWAY from Conditioners that USE Transformers. A Good Line Conditioner WILL make a Difference in ANY system. Try Different ones (Comparison Demo) and see which one makes the Biggest Difference in Your system (different ones due different things)! Good Luck.

The cinepro really made a big difference. The noise floor was lowered considerably. Also the music seemed to have more impact. Large storage capacity, 1.5 Kva, on the ten amp model. My friend and I both bought one after doing a listening test that lasted about, well we had barely enough time to turn around.

The Shunyata Hydra is tremendous. All of the products you mentioned are pretty good, but the Hydra is a different level of power product.

It takes about five days to break-in but when it does the difference are huge.

From my limited experience with various PLC's, i think you notice the biggest difference when you take them OUT of the system. Many of the improvements are subtle and take some time to notice / get used to. When you remove them from the system, you can then notice all those subtleties that are no longer there. The lower noise floor, ticks, pops, etc... from other devices in the house being turned on now become FAR more apparent.

I also think that PLC's work FAR better in congested living conditions ( apartments, condo's, city dwellers in hi-rises, etc..) or those in residences that have a LOT of people sharing the same pole transformer. Those that live in the boondocks or have very limited electrical usage around them may not notice near as much of a benefit. Sean

I've had good results with Mike "Vansevers" stuff.
