Canare 4S11

At $1.55/foot (Markertek), for a star-quad configuration, 11 awg aggregate conductors (4 @ 14 awg) per polarity, and polyethylene dielectric, 4S11 is certainly a bargain and it would probably take a lot of money to do significantly better.

The other bargain SC at barely over $1/foot is the Furez FZ124AS 12-4, which is a quad of 12 awg cables providing an even larger 9 awg aggregate conductor to each polarity. These feature a rope lay construction using both 27 awg and 36 awg, 4-nines, OFC wires, and foamed polyethylene insulation (FPE - which is unusual for budget cables). I am surprised more folks are not trying this one out - let us know what you hear if you do try it.

I just bought some Canare 4S11 at this place for $1.16 per foot.  The lowest price by far that I found anywhere!  https://www.performanceaudio.com/accessories/cables-connectors/bulk-wire-cable/speaker-wire.html

exceptionally good sounding wire at a ridiculously low cost

biwire ready too...

i have a set shotgun biwire and another non biwire set i use in my Vintage room, excellent neutral wire i got from Blue Jeans here in Seattle. a super value. great thread

I was always under the impression that the higher the price, the better the cable.  The fact that a $130.00 pair of speaker cables bested a $1500.00 pair should be a lesson for everyone regarding price VS performance. 

You don’t always get what you pay for, and that’s true for other components as well.
