Moving up from a Node 2i

...but most of us are curious about a solution that is between $1,000 and $2,000 and if that will produce objectively better SQ.

True.  Outside of measurements it’s all subjective though; I’ll just quote myself from the first page of this thread:

FWIW, I don’t think the U1mini is an upgrade as much as a nice side-grade to get a great app and excellent support. Upgrades to DAC, amp, speakers/headphones would yield more significant improvements.

Some don’t like the Lumin app, but it was one of the selling points for me.

I don’t see any references to support for WiFi in some of these “better” streamers. If WiFi is a requirement, what would be a recommendation for an upgrade from the Node2/2i?

Different digital methods could make the difference.
Do it over using same methods of transfer.

It’s hard to compare with all the permutations we have for connecting our streamers and DACs. Finding the most synergistic digital path is key for me when testing, not necessarily comparing the same connections. The Lumin U1 Mini has 5 ways to output digital; the Node 2i has 2.

I’ve read many forum posts that say the Lumin U1 Mini’s AES/EBU output may be the best sounding. I couldn’t test that; I don’t have a DAC with an XLR input for AES.

I found the best synergy, and subsequent sound quality, for the U1 Mini to my RME ADI-2 DAC was USB. A DAC with a lesser USB implementation may do better with S/PDIF or AES.

The best sound quality out of the Node 2i for my setup was S/PDIF-Coax to the ADI-2 DAC.

Sound quality between the two connected this way, subjectively: I like the U1 Mini better than the Node 2i, but it isn’t a huge difference. They are both very good.

Cheers,
Mike

Don’t let WiFi, or lack there of, color your decision making process. Assuming that you DO have WiFi in your house, all you need is a simple WiFi extender. They can be had for as little as $30. If you go to Upscale Audio’s website, and look at their streamer selections, you’ll see that for any streamer that is Ethernet only they recommend a simple extender easily available on Amazon. I have a Bel Canto e.One Stream and I’m using an old Apple AirPort Express WiFi extender and it works like a champ. 

My TEAC streamer does not have a wifi option. I used one of these to create a wireless client which allows me to run Ethernet cable from the client to the streamer.  25 bucks from Newegg.
