Hi, as per an AA recommendation, I just bought and installed the RS flat "mega cable" (http://www.radioshack.com/product/index.jsp?productId=2104178) and it seems to have bested my Synergistic Research (basic) alpha quad cable with better bass, clarity, slight air, resolution, etc.
Buying the fifty foot roll, I biwired (VAC avatar to Dunlavy SCIII's). These cables were poo-pooed by AA resident cable moderator who stated that their geometry and the plastic casing they're housed in does not support a good sounding cable, but my ears tell me otherwise.
Two questions for those knowledgeable. Would twisting the (flat) cables, sort of like an old fashioned telephone cable, ala a twisted pair improve the sound? And why do these cables sound so good right out of the box? I was surprized and expected them to sound much more bright and harsh than what I heard.
If anyone has a spare $25 or so they want to experiment with, I'd be curious about your opinions. Happy listening.
