Cables I opted for the Groenbergs Quattros that Klaus is selling and I will bi-wire the 80 to see what I can get out of it in terms of quality.
You've been conned.
1) It's copper. It's transmitting a very low frequency signal and it doesn't take much to properly shield a cable at these frequencies, assuming the amount of copper is sufficient to comfortably move the current.
2) Bi-wiring is the single silliest concept in the history of silly concepts that audiophiles embrace. Anyone that buys into this needs an intro course in electrical engineering, specifically a quick into on node voltage analysis. It's the same fricken signal on both posts of the speaker regardless of whether or not the bridge exists as a gold plate between the posts or two spades connected to the same output terminal on the receiver.
