Bluesound node 2i


Hi all

My Audio Research CDT1 is apparently unrepairable so I've been thinking about replacing it with a network streamer instead of another transport.  The local audio shop has the Bluesound Node 2i and it has a digital out that I can plug into my DAC, so it seems like a possibility.  But then the sales person said something that seems a bit strange to me: he claims that the sound will be much better if I plug it directly into the router than if I let it use the wireless.  Does anyone have any experience that would back up or refute this claim?  I admit I am a Computer Scientist not an Electrical Engineer, but I would have thought that any decent wireless streamer would buffer the input that came in and I think my DAC buffers and re-clocks whatever input it gets, so I'm not sure why this should matter.  For context I have Google WiFi and 450 Mb per second service.  Any other streamers I should consider? I know a lot of folks seem to like the Audiolab 6000N. Thanks for any comments.

I have one issue with Bluesound stuff.

You will see this in all of their promotional product descriptions:

"...the NODE 2i connects your gear to all the music ever recorded."

Why would they make such an obviously false claim?  I don't get it.
I own at least 100 records that are not available from Tidal or Qobuz.

Not saying it's a bad product;  I know that lots of people like them.  

Does this bother anyone else, if even a tiny bit?
The Node2i connects to more than Tidal or Qobuz. Have you checked Spotify or Amazon? Or the other stream sites you can access with the Node2i? 
@howardlander I purchased a Node 2i about 2 months ago and have really been enjoying it along with a Qobuz subscription. I have Cat5e cable run throughout my home by me when our home was being built a few years ago going to my network closet, so I had a wall outlet where my system is located. We live in a rural area, homes are spread out in farm country so wifi is pretty sparse, but I feel it sounds better, more open with the ethernet. I tried both the 5ghz wifi and ethernet, and I have a brand new ASUS hi-end router. I have a AQ Cinnamon ethernet cable going from the wall to the Node, probably overkill but it sounds great. I also picked up a Nordost Purple Flare power cord for the Node. Now tonight, I added a Chord Qutest DAC and Oh my, a whole new exciting world. 
Making the switch from wifi to ethernet made mega-differences in my Node2i. Do it now. Even a cr-ppy ethernet cable will make a big difference.
