Shunyata vs Richard Gray Power Co vs Chang???

one you haven't mentioned in your opening is the 'powerwing' from audioexcellenceaz.com.it was given a 'brutus award' on the positive feedback website. i have tried and owned the ones you mentioned and the powerwing is far superior..imo..in my system.it is both a conditioner and has surge protection also. alan kafton,who makes the audio dharma cable cooker, is the creator of this super conditioner. he will,i believe,allow you an audition of the product. you won't be disappointed...the last gentleman who tried one on my suggestion,bought one.

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!

Really appreciate your comments above.

I'll look into the Power Wing as well!

I happen to have an older LC-1 on my Naim CD player, but I didn't think it handled surges as well??? I was VERY pleased with the results after changing the stock cord.

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.
