I want to replace the router/modem Comcast with a high quality for streaming

@fastfreight  Yes, so long as there is not a metalic Ethernet cable that is going from inside to outside.  Then the only thing you have to worry about is long Ethernet runs.  Some are lucky enough to not need Ethernet, and can run their home 100% on Wifi.  Those folks don't have the same concerns.

Please remember that for power protection the NEC and whole house surge protectors still recommend surge strips at the point of use in addition to anything in your panel.  If you live in a relatively safe area you may not care but here in the south where we are prone to lightning strikes I recommend extra precautions.

@lalitk Yep, that is what I had to do.  I've done that every since I had roon but I thought that with a modem with 2 ports I might be able to eliminate one cable and one connection....but I think the modem has 2 parallel 1 Gig systems as opposed to 2 ports into the same system.  I've never gotten around to buy a nice cable to go from the modem to the router so I'll order one today.

thanks,

Jerry

Jerry…I am using 50FT LinkUp Cat 8 - 22AWG LAN cable from Amazon. The 22AWG version is pretty stiff so no sharp bends. The 26AWG version is more flexible. 

Sure. The fundamental improvement it offers when compared to the other routers I auditioned is a very significant reduction in the noise floor. I hear all of the musical benefits one would expect from a darker background: deeper and more realistic bass, more natural expression of note overtones and decay, better presentation of spatial cues and more “natural” location of instruments in the soundscape, and I hear more deeply into music to discover things I’d not heard before.

For reference, my digital path:

router - generic cat-8 - etherregen - DHLabs eth cable - Aurender N200 - Von Gaylord Legend SPDIF & DHlabs USB - Devialet Expert Pro - Reference 3A MM de Capo BE
