Nice system Ajahu, but I beleive that the Wilson Benesch Act One would really deserve a better amplifier. I think that a Mark Levinson No. 331 or 334 would be a perfect match with the rest of your system and macro dynamics would not be a problem anymore. Also, I would recommend that you should try the interconnect and speaker cables of Harmonic Technology (Magic Link One and Pro 9 or Magic Tweeter/Woofer). It would be a magical combination with the Fantasy power cords.
Happy listening!
