Can a wall socket dramatically improve sound? Yes

I finally got an Isoclean ICP-002 wall socket installed today. At the risk of restarting the usual drivel that ac cannot be so simply improved, I would simply say my sound is greatly improved.

I was already using many components of the Isoclean filtering system with great satisfaction not unlike the rave review in 6moons, although I have yet to get the transformers. The improvement with the wall socket is greater than other improvements I have gotten with these components. I am frankly shocked. The noise floor is lowered with resulting improved detail that lends more realism. The top end is very clean and extended and the leading edge is startling. The sound stage is totally encompassing.

I treated everything with AudioTop before installing it.
