Audphile1,
Yes as you point out, Supra cables are really good for the money, and there are better cables than the Supra cables. I think it’s important to highlight high quality cables at a more affordable price, as everyone deserves the benefit of good cables regardless of price point, or as important, good cables for a lower cost system.
I’ve found really good sound from Supra Cables (I have the Cat 8 Ethernet, Excalibur USB, 2.1 8K HDMI, and the same can be said for DH Labs, Zavfino, and Oyaide Neo.
All the best
