Connecting a streamer via an Ethernet cable

@surfmuz
Funny, you said you thought it wouldn’t matter on a inexpensive  streamer and my reaction is it would matter most on a inexpensive streamer. My reason is that a high quality streamer has all sorts of buffering and retiming built in and works at making up for incoming deficiencies. 

Ethernet over Power line devices can put a lot of noise into your mains (be especially wary if you are on the same ring main as your system).

That being said I still prefered that and Ethernet cabling over WiFi in my system. Then one of my power line adapters blew and I ran 10m of Ethernet back to my modem and took the powerlines out. This was best of all for me.

Wifi is a good solution if you have no neighbours competing for your channels and a strong internal network. In all other instances ethernet or fibre are preferable. Nevertheless great care needs to be taken to suppress RFI/EMI when using ethernet and on fibre the conversion quality at either end is crucial.

I have a Naim Muso Qb which is all-in-one. It runs 96khz in wireless and 192 wired. So wired matters.  

+ on the Mesh suggestions. I been dealing with this for years as modem on one end of tri level and my main unit on the other with many drywall between. First just a modem/router, then dedicated router then extender finally to Mesh. The first mesh node hard wired to modem and in a position to have line of site to the 2nd node down the hall and all the way to other end of house. 3rd node next to main unit and in line of site of 2nd node. Streamer hard wired to 3rd node. Sounds great and is reliable. The only thing I might do if I want to burn more cash is convert it to optical at the main unit but right now Qobuz rivals CD and my vinyl setup. I is a happy camper.
