Ethernet Cables

Cat 8 - better shielding. I highly recommend Supra CAT 8.

ViaBlue 7’s are much better than the 8’s I had.
Replaced my Supra USB too.

I followed his advice and am loving the improvement in SQ.

For the money Supra CAT 8

If the builder wired your house or office with standard ethernet cable in the wall, will using Supra CAT 8 or ViaBlue 7 from the modem or router to your system make any difference?

Just asking...
