Walk me thru upgrading from my BS Node

You never made clear if you require a built in DAC (not recommended.)

@poke33 

I need the singular physical box to be reasonably small

Other questions....

1.) Audphil1- I have a Wireless Extender...am I correct in assuming that if I position the extender close to my set up and use an ethernet cable to connect to the BSN my sound quality would improve? 

2.) Blisshifi- Just curious, does NAD use the BS UI for Qobuz

Thanks to all for your help!

@poke33 I wouldn’t assume wiring the BSN would improve sound quality. Only way to find out is to try. In example of AURALiC they typically sound best wireless.
Remember the Node is very good for what it is and what it costs.
But you’re looking for an upgrade. If you have a wifi extender in the proximity of the streamer don’t limit yourself to wireless only.

I would seriously consider a DAC with a built in renderer and Roon as your music server/database/UI as opposed to a streamer with a built in DAC.
Or consider separates - streamer, something like the Lumin U2 Mini and a good separate DAC. My reasoning for it? Streamers are essentially computers and as such their designs are emphasized around software/OS. A dedicated DAC or even a DAC with a built in renderer like Bricasti, Weiss or Mola Mola are designed with emphasis on DAC quality without any need to worry about the streaming UI.

Now, there are ultra high end all in one units where I’m sure all the due diligence was done in R&D and they may be a completely different ball game. But we’re not talking about those with a $5k-$7k budget. These tend to be well into five figures and more. 
That’s just my $0.02.

To the OP: Lots of info in yesterday's discussion  "NODE as a streamer". It will save me endless repetition. Life is too short.
