I tried the Sorcer unit last year. I read a positive review and called the owner (he is local here in Southern California) . He was very generous with his time explaining how he thought the unit works but I really didn’t understand anything he was telling me. I kept the unit for a couple of weeks trying different configurations. Unfortunately I couldn’t hear any difference in my 2 channel setup or my home theater system . I discussed with Bill and he was surprised I couldn’t hear any improvement. I returned the unit for full refund. I do have a Torus RM20 Bal isolation transformer and have dedicated Powr lines to the equipment. The system is particularly quiet so should have heard any changes. I’m sure the units have worked well in other’s systems as described in previous posts but it doesn’t work in all systems.
Add-Powr Power Conditioner Review
