Actually, the Supra sword super-duper cool technology is not new at all. Opposing signal transmission has been around for quite along while for inductance reduction/elimination. LAN (RJ-45) cables utilize this phenomenon. Those DIY LAN cable speaker wires we have all seen on many sites specifically mention that when terminating the 4-pair 24 gauge wires...you use one from each pair for the +, and one from each pair for the -. Simple aint it? CHEERS!

Dfrost:Had you considered auditioning either? You might add Purist,Stealth MLT or others with a slightly warmer/fuller balance.Have you dealt with the Cable Co previously?
You may find the Nordost slightly elevated in the highs.Whether this compliments your system is another matter.

Threshold does confirm they do not recomend MIT speaker cables with their amps, for the reason you described. This makes the decision a whole lot easier. Thanks for the heads up. It seems strange though, I have been using these mh770s (MIT) for years with these amps, with no issues, but my previous amp (Threshold S 500) did overheat as soon as it was hooked to them.

I agree if you are looking at $5000 cables then investing that elsewhere in the system is probably a good idea to consider to get the sound you want.

My opinion in general, not knwing your system, is that once your equipment is well matched to your tastes then you should be able to find an IC for 10% or less of that amount that works perfectly fine.

But if you must spend $5000 then buy one used, do not overpay, try it and then sell it and try the other if not satisfied. THat way you will know what works best without throwing money down the drain, unless you just have so much money that it doesn't matter to you.
