Budget Balanced Interconnects

I'm looking for a pair of reasonably priced, balanced interconnects to run between a BAT VK30 pream and an ARC VT100mk2 amplifier. Probably need about 3m length. Used or new - doesn't matter, but don't really want to spend more than $300. I'm wondering about Innersound cables, which are really reasonable ($80 up to 10 feet). Anyone know these? In general, I do like the Harmonic Tech truthlink IC's. Can I reterminate a pair of speaker cables into balanced IC's (perhaps add shielding???). Thanks for your input!
