Inexpensive speaker cables: any experience?

I very fortunate be bless with golden ear. I throw perfect pitch when on the mound and cut with finest Japan steel. I use Odin cable in reference system. You might have have mileage I might use kilometer but it very good cable. Good cable need be heard not easy explain but you give me good mushroom I tell you all about cable.

I’m using Duelund 12 g double runs. It gives a very natural presentation…

I use install gear 12 gauge pure copper from amazon, sounds pretty good and cheap, they also have a 10 gauge which is quite more expensive which i'll be upgrading too soon, they also sell smaller gauges also but i would only stick with 12 gauge and lower, unless you get a 14/4 cable and double up the wires would be like 10 gauge maybe 8, pure copper is all the same, copper is very good, pure silver is better and pure 24kt gold is the best

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...
