Shunyata vs Richard Gray Power Co vs Chang???

You might consider the Foundation Research LC-1 and LC-2 passive and dedicated in-line power conditioners.

In the Aug. 2003 issue of Bound for Sound, Marty DeWulf called these simply the best that he's aware of and he's been a stickler for line conditioning for the last 11 years or so. He bought the evaluation units and sold his old units.

That was the original version of the LCs. About 7 months ago, I sold my old versions and purchased the latest LC-1 and LC-2 versions. They are simply 2 to 3 times the improvement over the original versions which I've owned for 3 years prior to these latest ones.

Everybody's AC is dirty. Clean it up!

-IMO

Encyclopediabsh, I don't believe the LCs are meant to do anything with power surges. I believe that would be the job of a power regenerator or some function like that.

But I can assure you that if you were very pleased with the results of the old version, you should be nothing short of amazed with the new versions.

-IMO
