Iceraven: Why should I explain why? I didn't design the cable, and you can read it all at the MIT site. I tell you what, I will now. It's what you said, a form of LCR circuit that's in PARALLEL with the signal's path (i.e., across the positive-negative conductors)...Transparent Cable supposedly uses a series resistor, besides some form of LCR circuit, I gather. The ones I've heard from them do sound like something is in series, to me. Lots of things are going on with the design of MIT cables (and it IS patented, for what that's worth), and I'm not an electrical engineer (my brother is, though). I AM a speaker hobbyist, and know that a Zobel filter is used in parallel with woofers, to gently roll off their response BEFORE crossover. Now, as to WHY this works with cable, I can only assume the stated methodology at the MIT website, is somehow working (and that essentially all of the significant rolloff occurs untrasonically...but then, rolloff isn't the only thing the termination networks do, as you observe). I can also say that these won't work for all equipment, but when they DO work, it's better than ALL other cable types. ICERAVEN, YOU CAN DEMO THESE FROM TCC, OR JOE AT OVERTURE IN DELAWARE, AND LIKELY DOZENS OF OTHER PLACES. I recommend you try, if you have a solid state amplifier, or if you otherwise find your music lacks "weight", "slam", and "duration". If it doesn't lack these things, then you might not like what most MIT cables do in such a context.
