I just posted the below comments in the LCD-X thread but it applies here as well. As indicated, note that the October issue of The Absolute Sound had a very favorable comment about the WyWires Red:
To me the WyWires Red did the trick -- cleaner airier treble, coupled with greater transparency across the board and tighter bass. Overall faster and cleaner too -- faster transients. And I had been using the Moon Silver Dragon, which was an improvement on the stock cable. But the WyWires Red was, imo, quite a bit better than the Silver Dragon, as per above. The Silver Dragon did have a bloomier bass which gave the impression of more bass, but it was just not as tight.
Also, with the cleaner treble the WyWires took away a bit of the darkness of the LCD-X, in a good way.
Thank you Mike Mercer and others for spreading the word on this cable. Also great service from Alex and fast turnaround in about a week. $299 for 5 ft.
BTW, the October issue of The Absolute Sound, p46, had a brief discussion of the WyWires Red at the recent Newport audio show, by Jim Hannon. He noted that the WyWires Red had "far better clarity, definition and spaciousness than the stock cable in an A/B demo". And what was the stock cable and headphone used? There's a pic but it's hard to tell, could be either the LCD-X or a HiFi Man headphone.
