Inexpensive speaker cables: any experience?

I used monster cable, I then used a bi-amp bi-wire set up off using 10 gauge BlueJean speaker wire. There was definitely an improvement. I then bought AudioQuest Oak bi-wire/Bi-amp speaker cables and the sound totally changed. Much smoother, with better separation and color of tone. Unfortunately the only way you will know is by testing wires in your own system. 

my 2 cents (consistent with some comments already made...)

lots of decent copper stranded cable out there, branded or unbranded, just get right gauge, terminate well, make tight connections - solid core copper maybe a touch more lively but once again not a difference worth chasing for most

of course if just for curiosity, just want to tinker and try for fun, then have at it... make yourself happy

many options out there all work fine, many makers/sources named already, i would throw in belden 9497... differences are non existent to very very subtle unless one has an exceptionally high resolution system, even then, changing speakers, source, or even interconnects will most likely make more of a difference sonically

it is very hard to do quick a/b of speaker cable... (the ava abx comparator does allow this)... once you set up for controlled a/b, better blinded, it is really hard to reliably tell the difference

above all else, i would say, just enjoy the music...

Anyone who quotes a reviewer on their eBay listing, but doesn’t name the reviewer, is best to stay away from.  Already being unethical in their listing, wouldn’t want to deal with them.

‘NOT saying all eBay speaker cables are bad.

Spend the money on treating your room instead. 

About thirty years ago I bought some stranded, silver coated, 12 gauge wire. I still have two, ten foot lengths with the ends tinned with silver solder. While they aren’t on my main system, they were until I bought a pair of AQ Rocket 88’s.

All the best.
