Is a Power Wedge 116 any good?

In my opinion,  the relative sonic benefits from various power conditioners depend heavily on the power supply designs within the equipment you are using. There is no consistent answer to "which conditionernis better". I have compared many, and the Power Wedge continues to be as valid and sonically beneficial as it ever was. They were way ahead of their time.

I owned one of these power strips. They work well. 

I am a dealer and I used to sell the Power Wedge when there was not a lot of choice. ( Tice) 
The Power Wedge is dark and compressed. There are a few good ones out there that would make quite a difference if your system is resolved.
We sell some for home theater that are not the best sounding. (Panamax, Furman, ATC, and Watt Box)

I think the power wedge is fantastic does a great job, especially with digital.

I had one it was good 30 years ago today no big deal.
