How good is Blue Sound Node 2 in WiFi vs Ethernet connection vs external CD player?


I'm considering purchasing the Node 2 in order to use Tidal in my external DAC that is much better than the internal DAC.  My objective is to have access to CD quality via Tidal in my external DAC.  However, my question is if I do not use a Ethernet connect but just use WiFi for streaming tidal, will the quality still be as good as my external DAC playing the actual CD's?

I purchased the Node 2 not as a stand alone, but as part of the whole house Bluesound system.  Arafiq  asks a good question .  I would point out that Apple is discontinuing Airport Express.  I have a second generation ATV and have tried using it as a digital transport but It sounded muffled in comparison to the Node; perhaps the current ATV  is better sonically.  
  The Node2 DAC is really pretty good,, considering the entire component sells for $500

Been using a Node 2 for streaming HiFi Tidal since March but decided to try a couple of external DACs to see/hear if it was the worth the upgrade. I also wanted to upgrade (or replace) my old CDP at the same time so I figured I'll find a way to upgrade the sound quality of both. Borrowed a friend's Bryston BDP-1 and ordered a Cambridge Audio DACmagic Plus, both with two coax inputs. All else the same, the improvements were noticeable. I expected the BDA-1 to sound a lot better but the DACmagic Plus - oversampling to 24/384kHz, sounded real good so I decided to keep it. Hard to explain but in my system the external DAC added more "weight" to the mid/lower bass for both the Node 2 and my CDP. If my budget allowed I would have seriously considered a BDP-2.

@wtf  Assuming that you've done an A/B comparison between Apple TV and Node 2 in the same system, what aspects of the sound improved with the Node? There are not too many people who have used both the ATV and Node in the same system, so I'd be very curious to learn about your experience.
@arafiq .. the Node 2 is more refined and nuanced with a better sound all around really. Apple TV’s resample everything to 16/48 which may be the reason they sound as though something is missing in comparison. Perfectly good for streaming Apple Music though.
@wtf  Sorry just saw your reply. I guess I should just get one and try it out. Magnolia Design Center carries this brand, so I can always return it if not completely satisfied.

On a secondary thought, I wish someone can build a quality streamer without an internal DAC. I bet the price of the Node would be half if it were not for the built-in DAC.

Thanks for the feedback.
