Maril555, yes I do like the Furutech stuff and it is somewhat expensive, but less than bi-wire Cardas GR in 10 ft. lengths. Furutech also makes less expensive bulk OFC cable. The Furutech cable can be purchased from Partsconnexion, who has sale pricing of 15 to 20 percent off about 3 to 4 times per year.
I also like the Harmonic Technology cables, which you could probably purchase used for less. I would recommend two single runs for your bi-wire run. I have used Pro 9+ for LF and Pro 11+ for MF/HF and that worked out pretty good. Pro 9 Reference is good in the bi-wire configuration. These HT cables come up for sale used in 10 ft. lengths occasionally and you could purchase one 10 ft. length and then run jumpers until the second opportunity comes along. Then, if you like the single wire better, simply sell the second pair. If you only have one set of binding posts at your amp, you can still run double cables, just stack the spades or go with a spades and bananas set-up. The Speltz option would be a very economical way for you to try single wire and biwire options in the length you need. There are a host of other inexpensive options if you search these threads, including DIY with CAT5, Canare star quad, VH Audio bulk wires or others.
