Any Cambridge users on Tidal? Differences in Tidal levels?

I use wifi. Minimal issues especially with the last few firmware updates.  
Having said that, if I had an ethernet line in the room I would likely use that. 

Thanks all for the help.  I find the Cambridge machine a bit cranky on start up to connect to my internet address.  Sometimes it takes a couple tries to lock which is kind of a PIA as the full system is now on a power conditioner so one on/off switch does it all.  The cable company is under contract and supplies the router and a TIVO to every apartment and while the router does not have an Ethernet connection (75 ohm coax to the TIVO)  in the back the TIVO does.  It would be about 30 - 35 feet and through a wall to get from one to the other but I've wired surround speakers through a wall before to hide cables so that's not all that big a deal and I'm considering it.  I think it would be a better data connection for higher rez radio stations and Tidal hi-fi anyway and Ethernet cable is not very expensive.  ..   Any opinions greatly appreciated.

Cable, you definitely want to use a Ethernet cable if available. 
We are living in a flat in the city centre (120 years old): there are 590 WiFi’s around us interfering with each other. There just has to come a friend with an old iPhone, join your wifi and the transmission rates drop down; and a zoom conference in the attic and a Tidal don’t mix well on one WiFi network. It’s not so much about bandwidth but stability (and peaks). My husband and I hard wired the whole place ...

Thanks for that Joern4 My Cambridge sees about 20 wifi names or so. I’m waiting for a Technical Support person on the phone with our cable company to find out if I can use the Ethernet connection on the back of the TIVO to network from even though it’s a room away. Now on hold for 46 minutes waiting for someone.

OP here.. as a followup I am going to hard wire the Cambridge as my next project. I have some Ethernet coming from Amazon (probably Chinese) Cat 7 flat and some coming from Blue jeans which I believe is Belden and Cat 6a. Both with capabilities far beyond anything that is going to be around for transmission this year. FWIW, Ookla speed test via wifi to my computer in the same room as the Cambridge was 201 down and 21.5 up. I expect both cables in next week.  Want to get that done and finish burning in new power cords and conditioner and such before I sign up for Tidal..   want to get get evrything else out of the way.
