Great advice, thanks. I will definitely go with the longer balanced interconnect. As a bonus, it sounds as though a decent long interconnect is cheaper than decent long speaker cables. I like the suggestion to spend the money on just interconnect now, and go with better speaker wires later when budget allows.
For future reference, I would love to hear what other Classe owners are using for Interconnects and speaker wire.
p.s. How do you go about demoing this stuff (wire)? Local stores have a very limited selection. Do you just buy a bunch of different stuff here for comparison, then sell the losers?
