Russ,
I had the Remote Sense cables for a while. They were much better than the Nordost Red Dawn Rev II, and I'll put it against many cables costing twice as much. I agree with Rafael, they may not be in competition with the best cables out there. I recently got the Stereovox Reference cables throughout my system and the level of detail, speed and transparency I get from the amps with these cables is simply uncanny. But again the Stereovox Ref SC is 5.4x the price of the Remote Sense.
I also talked to Simon regarding to go mono-block or go biamp when I was getting the second amp. He suggested to go with mono-block. The improvement in sound quality was so great with the mono-blocks that I now doubt that bi-amping could have made so much of an improvement. This might be a different story in your case, but I think mono-block is the way to go for the technical reasons explained in Spectron's site.
My brother finds my system spooky because he says that the musicians are for sure in the room, he knows exactly where they are playing in reference to one another, but he can't seem them. And that freaks him out! He said that after I setup the mono-blocks.
