My vote is Anti Cables, they are hands down the best affordable speaker cables. I just upgraded to the new Level 4.2 flex model and it was about $500, and they are very noticeabley better then the level 3.1 anti-cables I’ve had the last couple years, like night and day better. I used to have Audience AU24, wire world equinox, and a few other much more expensive cables, the Anti-cables beat even the Audience at less than half the price by a wide margin and that was before the new 4.2 flex model.
Anti-cables have incredible bass, great imaging and separation, detail, just awesome especially since they are so much cheaper than many lesser cables. Also they are thin and I can get them to run through my speaker stands so it looks really clean. I’m pretty sure they let you buy them and send them back if you don’t like them like a trial or something, but trust me you won’t be sending them back. And they will terminate them any way you want, I ordered mine with bananas on the amp end, and their excellent solid copper spades on the speaker end with biwire layout.
I only use their speaker wires, all my other cables are Acoustic Zen absolute and matrix reference, Krakatoa, which I swear by and are very expensive, but the Anti-cables are my favorite speaker wires by far.
