After trying lots of power cords ended up with TG Audio HSR-A Gen.II with an Audioprosm Quietline plugged into the same duplex outlet. The I seemed to constrict dynamics and didn't sound as open. The PS 300 sounded electronic and the hydra also squelched dynamics. I would also love to try the stealth as I trust the review who reviewed it on enjoy the music and he heard the same things I did from the hydra.
