Got a Node 2i, what's next?

So, I admit that I'm not much of a digital guy.  I ordered an Node 2i for the main HT system mostly for Amazon HD.  Much better than roku --> Denon AVR-X3600.  I liked it so much I ordered another for my previously all analog 2 channel system.

It's not bad, and convenient. Not even close to vinyl on the same release and level matched recordings, but then again, I didn't expect it to be.  I keep reading about how you can easily improve the sound by adding in an external DAC.  Here's where I get confused.

I don't want to spend a lot on a DAC, because at best it's a secondary source.  I'd feel comfortable in the $500 - $1000 range, but I'm really confused over the options and how they relate to sound quality.

First, r/2r vs I guess delta sigma?  What are the sonic advantages of either, there are widely differing opinions there.  I understand how each works from reading around, but how does it relate to sound quality?

Second, multibit vs whatever else.  Same basic questions, what are the basic sound characteristics of each?

Third, oversampling or no.

And lastly, what bitrate/bit depth is considered adequate?  24/192 seems to be standard but some dacs only have 24/128 over optical.  Will this make any difference real world with HD streaming?  I also have an old NAD cd player with coax digital out I might want to hook up for kicks.

I've researched three so far, the Denefrips Ares II, , the Schiit offerings below $1K, and the Cambridge Audio DacMagic 200M.  I would like to have balanced outputs to keep the digital circuitry as far away from the analog stuff as possible.

Thanks in advance for your answers.

Might want to check out RME. Can likely find a demo ADI-2 demo with full warranty right around 1k. Great sound and TONS of features which you may or may not use. I find the EQ and loudness function useful at times.
Just curious what is you vinyl setup you are comparing to?
Thanks for that.

My vinyl setup is a modified VPI TNT4 (air bladders are connected to an air compressor with a precision low pressure regulator) with TNT5 bearing, Eminent Technology 2.5 modified for use with air compressor, also with a precision low pressure regulator, Current cart is a retipped Supex SDX-1100r thru a modified Supex SDT-722 stepup transformer into the MM section of a Herron VTPH-2a. I also have a NOS Audioquest B100 on another armtube that I run straight into the Herron MC stage, plus a few other cartridges that don’t see playing time right now.

Multibit is just a propriety filter on Schitt DACs.
They don’t do DSD.
Isn't DSD Mostly for computer interfaces?  If so I don't need it.

I'm not really interested in a headphone amp, or signal processing on the dac.  Not that I would rule the features out, but I probably would never use them.

DSD is the preferred repro method nowadaze, talk to Cookie @ BlueCoast
 You can play it on most streamers starting at a $100 Ras Pi 4. No stoopid computer. Your vinyl set up is like a Bentley  and your digital a Yugo.
Do you want to hear what’s out there?
I’m not sure.
If you're not interested in loudness you don't ever listen at low volumes with full enjoyment.
Even on your Bentley class sys.
I have to get up and switch in a Loki etc. for that.

@fuzztone1,

I listen to vinyl all the time, very little digital except background music and in the car, none on my 2 channel system until I got the Node 2i.

I have a full featured preamp (soon to be replaced with a better one) that takes care of the tone compensation duty, but most of the time when I listen to my 2 channel system I don’t listen at low levels. When I do I switch in the controls.

In building reference DACs with both R2R and Sabre 32 bit chips each has their own sound.  The R2R generally sounds a little more musical, more dimensional, and a little more relaxed.  The Chip generally sounds not as dimensional but usually more extended top end, faster, cleaner, and sometimes quieter.  Trade offs aalways.
