I had been using Audioquest CV-4 w/ bananas on my Parker95 MKII's from my Decware Select. I noticed a thread on the Decware forum re:
using CAT5 or CAT6 as speaker cable probably from an old AudioAsylum rec. Just one twisted wire pair stripped out of the CAT5, stripped the ends (no connectors.)
I only have a short run 3-4 ft, this stuff might heat up in longer runs. I prefer this on an admittedly very low power amp to anything else I've tried.
Tried out the quite pricey NBS Omega from my HT setup but found I liked the CAT5 better.
Apparently the cryoed version is even better.
As always, YMMV.
