I've not found a more hard to predict outcome than speaker wire changes. Price and performance are not easily predicted ratios in my experience (admittedly, not vast.) Over the last few years, I've used Analysis Plus Oval 9, Kimber 4tc & 8tc, Sonoran Plateau Desert, cheap Monster $1 a foot 14 gauge, & Furutech FS-502 in a DIY cable. FWIW, I sure don't have the most resolving system, but it's no slouch either. None have been overtly deficient and all have their strengths. The Furutech is a stone winner in price/performance ratio if you have a system more slanted to the warm and inviting side of things. I wouldn't want to use it in an analytical, edgy system. I've been so impressed with the inexpensive Furutech, I'd like to try their FS-Alpha speaker cable next ($100 a meter, DIY.)
