RECOMMEDATIONS FOR AC RECEPTACLE

A friend of mine convinced me to purchase two PS audio Power Ports. Received them and installed them and almost immediately I notice my HDTV picture had greater clarity and it cleaned up the video noise. The Picture is awesome and the graphics didn't have those little jagged edges.
In the meantime, my music jumped out at me, with greater transparent detail, depth, and tighter bass. But I also noticed that the highs were a tad bit harsh especially on piano.
Just finished running a dedicated line with two circuits with an isolated ground. I understand that this will make my system sound and look even better.I would like to hear suggestions for AC outlets that will be an improvement over the PS audio Power Port, i.e. getting rid of the harshness. I know this will be very subjective, but I would like to hear what you guys have to say. I have gotten some great advice in times past.

BTW my equipment: Meridian 568MM.2, Meridian 518, B&W 801's series 80 with bybees, B&w cc80's sides and rears, B&w HTM2 Center channel, Velodyne Sub 12", Denon 2910 DVD, Earthquake Cinenova 5 channel with dakiom stabilizers, B&k 2 channel amp, Mitsubishi Diamond series 73" 1080p HDTV, slim Device Squeezebox, Monster Power HTS 5000.
Everything is looking good and sounding good but as you know good is the adversary of better. Waiting to hear
