Hmmm...never saw this one till now. Thanks Dan for the sticky; thanks George for the heads up.
IC's:
I've tried many, both XLR and RCA, but my favorite, simply for its beautiful midrange quality, is the Stealth Nanofiber RCA. If I had that cable in an XLR version i\I would be there...to me the XLR would win all ties due to the TP's natural balanced topology. But it's close enough that the cable dictates the choice, not the connection. The great actively powered Synergistic Tesla Series XLR's were demo'd on the TP (Accelerator, Acoustic Reference, to name two) but the detail they retrieved was not up to the tonality of the Nanonfiber's midrange. The Tesla's as speaker cables however...now we're talking.
PC's:
Again, I've tried a few, namely Lessloss, Black Sands Violet Z1, Synergistic Research AC Master Coupler, Michael Wolff Carbon. The Black Sands is my favorite..but only as long as the Lessloss is on the Modwright 36.5.
With my 36.5 front-end at Dan's currently, I use the Lessloss on the TP with my passive pre. I like the smoothness of the Lessloss, but prefer it at the pre, with the nice balance and slightly more aggressive style of the Violet Z1 on the TP. But then again, with certain tubes rolled in to the equation, who knows.
Too many variables, not enough time.
