The best speaker cables you’ve had

Kubala-Sosna Realization, which I own, and they are perhaps the most natural sounding I have heard.

Just a follow up. ''FURUTECH FS-α36 Flagship OCC HIFI Speaker Cable Fever Grade Audio'' Last week I replaced the Monoprice 4/12 cable on 1 side of my system to compare both cables. There's no compresence, the Furutech wins hands down. I loved my system setup as it was, but now, I've noticed a sense of clearness in the 1 channel.

A local dealer uses Nordost exclusively - makes every system sound better than they should,. 

I use Kimber 12TC, bi extended, clear and refined,  perfect for my system.  

^^^^^^^^^^^^^;

last weekend I pulled the other cable, now both channels have the Furutech. I can't get over how good this cable is. Worth every penny, the best upgrade I've done in years! I just might rewire my surround speakers.. Down the Rabbit hole again! LOL

unless you hear a cable in your own system you have no idea about its performance
