Fiber or Eithenet

Marco1, I’m using Snake River products now but used Cardas exclusively for many years. Cardas is a great company to deal with, I bet they would fix that USB cable for you.

I’ve got a selection of ethernet and USBs coming on loan from the Cable Company next week. Their lending library for cables is exceptional. You pay to rent the cables but the money goes on account towards a future purchase. I’ll report back what differences I hear. I already hear a big difference in the power supplies for the iFi LAN Purifier. The tiny one it comes with is surprisingly good, and breaks in almost immediately. Right out of the box, the $300 power supply is really closed off but 48 hours later is significantly better. More weight and better bass but the top end is still less open than the power supply it came with. I’m hoping another couple of days will change that. I also have the $100 power supply burning in on my AV system. Same thing with the sound being closed off immediately on installation but I’ll give it a week. I’m interested to hear the difference each of these makes. Free, $100 and $300 worth of power supplies from the same company. We’ll see, and if not better, then Amazon returns here I come.

Ethernet is fine. 

Remember, data packets pass fiber, electric, satellite on their way to you. There is no "stream", it is all sliced and diced and sent out of order mixed with all other crap.

Hi @marco1 I have the Supra ethernet as well as Inakustik ethernet cables but I prefer this over them both: https://www.amazon.com/AMPCOM-Ethernet-Screened-Connector-Playstation/dp/B07JC5D2B6?th=1

Inexpensive but really well shielded and the connectors can be found in higher-end models like AQ Vodka etc...
