You've nailed it. That is EXACTLY the same experience I have. What used to be "excellent" sound is just ordinary...the X4 Sorcer is a game changer.
The change is in the harmonic content brought out in the sound.
And, as a bonus, it is compatible with most other tweeks, AC cords, and power conditioners.
Power conditioners are fine for what they do - but that is all they do. They do not address harmonic content..
I have a Sorcer X4 and Wizard. The ADD-Powr technology is utterly and shockingly amazing in the breadth of tits impact in my audio system ....Whenever I unplug either or both, every time the sound collapses. It becomes just good sound - far below what was heard only seconds before. Sonic details, imaging, transparency, depth, sound staging, etc. disappear. When re-plugged, the Sorcer , within 5 seconds, restores it all.
I know a fellow audiophile that has two, yes TWO, Sorcer X4s in his system! He says that it took the sound to another level of sonic excellence, if that is even possible?!
Has anyone else tried the product?
