Do router and ethernet cables affect sound quality?

  1. You don’t play off the cable. You play out of local buffer. See my post here for a run down of a test setup and the associated video

  2. I don’t care if a manufacturer can find 1000 people that think the earth is flat.

Instead of spending anywhere from $400 to $1999 on an ‘audiophile’ switch I did all of this for $214:

Cisco WS 2630 48port GBe, 4 port SFP+ 10GBe switch ($65 on eBay)
HP NC 223 Dual SFP+ PCI-E X 8 NIC ($29 on eBay)
Dell R620 dual GBE Copper, dual SFP+ GBe daughter card from Server Monkey for $20.

Three SFP+ SR MM LC 10GBe transceivers and a 20 meter MM OM3 LC/LC fiber cable from FS.com for $100.

So not only did I do this for 1/2 to 1/8th the price of what the snake oil switches go for, I get at least 300% more through put and all the electrical isolation you could ask for.
