Ethernet cables

You asked, so my answer is no. I doubt anyone here has honestly heard a difference they could reliably distinguish on sonics alone. Some might say use CAT 8 because of the additional shielding but I am even skeptical of that. As a mid-point between super cheap and stupid expensive, I like these simply because of the connectors and build quality.  If you have a long run, consider optical/fiber.

@audphile1 I like boats are we Trawling now? There are no silly questions regarding Audiophile salvation!😎

I believe we are running a purse seiner….. sorry - couldn’t resist. 

on topic…. great sturdy connectors and verified quality assurance matter, and shielding….

My experience albeit somewhat dated is 50% DOA on Bluejeans

Suggested for APEX dCS streamer/dac ($32k), I have tried for 2 weeks with resounding success: Nordost QNet network switch & QSource Linear Power Supply and premium QSource DC Umbilical interface cables, all $6.3k.  This upgrade is really justified -although expensive-  .

Thank you very much for your time and your useful answers!
