System sounded a tad more laid back with the extra ferrites. What really sounded better is I removed my 598 from the same power tap on my AC regulation that my 568 was plugged into. Much more laid back soundstage now. Vocals even smoother with more depth and palpable soundstage. WOW! Could it be the 598 switching supply...or maybe the line filter in the 598 dumping supply noise to ground? Guess I still need to do more investigation. Does the 598 have a line filter? Will know soon I haven't opened it up yet. Its amazing how interaction between components on the AC power side came make so much of a difference sometimes.
