High capacitance usually rolls off the high frequencies, not the midrange -- plus, I didn't think the WW Gold Eclipse III was a high-capacitance design. Maybe something else is responsible for the reticent midrange; without more details, I couldn't say. Good luck, let us know if you track down the problem. One cheap way to see if it's the cables is to swap the WW cables for something different and see if the balances changes to your liking -- heck, some standard 14 or 16 gauge zip cord from the hardware store would tell you what you need to know.
Capacitance: Help me understand
I have been trying to match interconnects with my system. everyone keeps telling me I probably have a capacitance problem with the Wireworld Gold Eclipse III that connects my preamp and amp. I have no idea of what this is, but Isure can hear the effect it is supposedly causing, a too deep soundstsage with diminished volume from the center image.Can someone explain capacitance to me? I am not stupid, just clueless.
