Compared these power cords to the Synergistic AC Master Coupler and the Shunyata Research Mamba.

I tried all the cords and the stock cords on each of my components one at a time and in varying combinations. I now have Harmonic Tech Pro-AC 11 cords on all my components. My observations:

Synergistic - Very smooth and warm at the expense of some bass definition and extension. This was most apparent when used with my amplifier.

Shunyata - Very detailed and precise sound, but a bit too bright for me.

Harmonic Tech - I can't find anything wrong with these. Very transparent, excellent bass extension and definition. Very detailed highs. Personally, I would have liked a little more warmth, but I couldn't give up the definition provided by the HT's and go with the Synergistic.
