I found the DH Labs glass Toslink to be head and shoulders above my Supra ZAC Toslink, my Lifatec Toslink and an Amazon brand that was well received. I also got a great deal on some DH Labs HDMI 2.0 when on closeout of that line which was a nice step up on some WireWorld cables I was using. I could easily see the improvement on my TV. Not to be overlooked.
If I ever get the itch to try out that Shanling ET3 CDT, I'll try one of their USB cables.
All the best,
