I don't mean to wet blanket this direction; but in the last few months Furutech has released their 'NCP' versions of the GTX-D (R) duplex outlet. to my ears it is clearly a level above the GTX-D (R) outlets that I had.

if you are wanting the best. these are that.
and further; Furutech also applied the NCP tech to their top-of-line male and IEC plugs for power cords. which I had installed to at least as significant performance upgrade.

it's too bad this stuff matters so much; but no doubt it surely does.
Mike L.,
This past week I sent my unopened GTX outlets back and exchanged then for the new NCF version. I also sent back my PC's to have all of my original GTX connectors replaced with the new NCF stuff. (Pretty much cuz of your findings.)
Sometimes being ridiculously slow in setting up a new room has its advantages. Thanks for your insights.
