If I'm going to go off on a cord there right now, it needs be one that has an enveloping sound stage that encroaches into the listening position a tad, has great bottom end tunefullness and sweet highs... and all the other junk that should be there at those price points. Dynamics, weight, imagery, etc.
then the Flavor-4 may not fit your needs. When I had it running from Hydra2 to the wall I had the Audience powerChord from amp to Hydra. I found the Flavor to be a little forward on highs and thin in bass. It was extremely detailed. I'd say a bit too much so. Soundstage was pretty well layered but still, with images that were a bit thinner than I like. Of course in your system it may be different, since you know how it is with PCs, they don't sound the same in all systems. But just to make sure I was hearing what I thought I was hearing with the Flavor cord, I swapped the cords on the amp from Audience to Shunyata D-back to Acoustic Zen Tsunami Plus and the character of the Flavor cord was pretty much the same throughout. I don't know how important the cord is from the wall to the UPC, but with Hydra it seems to be the first cord to worry about, as I prooved with Taipan.
I think the new Taipan Helix is excellent. Very neutral, very dynamic. Shows the truth. I think it is an improvement from the previous Taipan as that one did seem to be a bit bloated in comparison to Helix. I find the Taipan Helix cord not to sound as fat as the older Taipan Alpha. FWIW.
Good Luck!!!
