Micca 14 Gauge Speaker Cables These bested $2000 cables in my system. Notice how I am saying MY SYSTEM.
Just another suggestion: I purchased Silnote Audio's least expensive speaker cables (Morpheus Reference II Series II @ $495) when I purchased my Focal Sopra 2s and intended to upgrade if I liked them. They were so good that I ended up just keeping them! In my system they just seemed to let the music flow more effortlessly and naturally. That was 4 years ago and I've significantly upgraded the rest of my system and these speaker cables have performed every step of the way.
I've since also replaced all of my interconnects with Silnote with great results each time.
Good luck and happy listening!!
