I recommend Anti-Cables, they are amazing and affordable. I used to have Audience AU24, Wireworld Equinox, even Acoustic Zen and then I tried the Anti Cables and they blew the rest away, way more open transparent, crystal clear, details that I never heard suddenly are audible, and the bass is next level, I’m hearing deeper subterranean and more detailed bass than ever before.
I think I have the Flex 4.2 now, but originally I had the cheaper ones when I tried them on a whim, I think they had a 30 day money back trial or something back then..
I still only use Acoustic Zen interconnects and power cords which are amazing, I did try a Anti Cables power cord and it was not very good, my Acoustic Zen Krakatoa is in another universe compared to the Anti Cables power cord which honestly is just bad IMO... But the speaker wires are easily the best bang for buck, I don’t even think of upgrading speaker wires anymore.
Maybe if I won the lottery I would try out Nordost Valhalla or some other crazy expensive cables, but for reasonable budgets you can’t beat Anti Cables IMO and they aren’t like wrestling with a garden hose, very thin and manageable, especially since they are pretty stiff you can bend them to whatever shape you need.
