Acoustic Zen Tsunami AC vs. .............

Looking for AC cord advice, preferably from someone who is familiar with the A.Z. power cords.

I'm looking to upgrade for my Halo JC-1 monoblocks. I've only "auditioned" a few AC cords so far, but none can seem to beat, overall, my Tsunami's in this application.

Can anyone please suggest an upgrade path, that is hopefully reasonable $$$?

Thanks to any & all.
