Second the Canare 4S11 note.
and another one.
With runs of 30-40ft in my main HT setup driving the Silverline SR15s (92db, 8ohms), bi wire is quite good... suplanting them with a pr of Canton two ways (87db 8ohms)I had to lose the bi wire approach and connect them up double stranded instead.
I also use a pr of Synergistic Research Sig 10 - x2 active bi wire cables as my main speaker cables with a variety of amps and speaker conbinations... primarily though with Silverline sonata IIIs 92db at <8, Odyssey Stratos Plus 180w, Butler TDB5150 150w x 5, Dodd mono blocks 120w BAT VK60 60w, Rotel 1080 200w.
The SR speaker cables are decidedly better than the Canare
BUT Canare comes in around a buck or so a ft. the SR Sig 10s new were around $80 per ft. I got mine for under $600 @ 21 ft.
Canares using two strands per terminal are a warmish sounding cable
going bi wired, using a strand per terminal, they become less hearty and not warmish at all.
The SR Sig 10s are about as neutral as Ive found while still possessing body, openness and balance that delivers fine imaging, bottom end and a very musical presentation without spotlighting, or obscuring detail. And all is conveyed with refinement and a very very low noise floor
w/SS or HS.
