Ignatz. Despite the claims to the contrary from Wireworld, its cables have high capacitance. The effect you are experiencing is precisely what I heard with an amp that has proved not to like high capacitance cables, and driving difficult electrostatic speakers. It is not so much a forward cable that may be the solution, so much as a low capacitance cable.
"Forward" sounding ICs and Cables?
I am currently using Wireworld Gold Eclipse III ICs and Stealth Premier Copper Cables. My problems is that since the Wireworld ICs have broken in I have too much depth in the soundstage on much of the material I listen to. Vocals sound as if they are coming from far behind the speaker, at reduced volume. Imaging and width of soundstage are great just too much depth. I have reduced this problem through speaker positioning but its not enough. I realize that the Dynaudio Confidence 5s I use are prone to this, but it bothers me. Any suggestions for cabling to reduce this problem would be appreciated.
