AC plug benefit?

Good point, Hdm. I agree.

I purchased 2 off Albert, great guy BTW and a pleasure to talk with, they improove things but dont expect miracles as what is huge change to one persons system can be subtle but better in another, all the same things will no doubt be better but its a question of how much.

Chadnliz is right, these kind of "tweaks" could give some improvements, but they are never "day and night" differences. That is one of the rules of high-end audio.
