Ddraudt, I have just begun experiments with it. It is plugged into the wall and two other devices feed off it. One is the HB Designs Acrylic PowerSlave with all analog device plugged into it and the other is a Japanese device with all digital devices plugged in. This allowed a simple with and without the WGPC.
With was definitely superior with all the properties of the HF cables but to a far greater extent. The soundstage is very wide, deep, and high, it is very detailed with no doubt as to how wide and where the marimba is, where the audience member who is coughing is including how far away from the performer, one can easily hear the decay of the notes in the hall, and the timbre of instruments is right on.
I want to move on to skipping the use of other devices in ac filtering, but having only eight outlets on the HF WGPC is a limitation.
I do wish the Hubbell 5362BLK duplexes without cryogenic treatment were used. I wish all could be zapped on the SR Tesla Coil.
Presently, I am using the spikes that come with the HF WGPC on an Accapella isolation base. I will soon be trying the StillPoints Ultra Fives.
