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.

Wow, lots of great suggestions.  On my short list so far is the Denafrips Ares II, the Musical Paradise MP-D2, and the Cambridge Audio DacMagic 200M.

I'm slightly hesitant on the Denafrips only because of having to ship overseas for ant waranty work.  I like the idea of a tube output stage on the Musical Paradise.  I like the Cambridge for price and completeness of features, and I can get up to 60 days trial depending on where I buy from.

Keep em coming, you guys are a great resource.



There are dacs out there that sound just as good as vinyl, read the reviews on the wyred for sound 10th anniversary. Go to their site and look up the review by 10 audio, the reviewer put it up against this VPI turntable with a 5800.00 Japanese cartridge and he said that the 10th anniversary dac was neck and neck with his VPI turntable. One of the most analog sounding dacs I've heard at any price.
I came from same place as you mostly vinyl, hot rodded lp12 and Herron phono. Since you mentioned r2r the MHDT Orchid might work. If you can solder caps are very easy to switch out, you can use 6922 and 6sn7 adapters which can help not being boxed in to one flavor. If you like what you hear you can sell Node and find a nice used streamer. If not the Orchid sells at maybe a loss of $200 and will sell in a day or 2, or find a used one. I've seen MHDT Havana sell for $400 or less its old but nice, I have the Havana and Orchid, Havana may be 80% of the orchid. I also have the current version RME adi-2 and can't say enough good things about it. I have not  felt the need to go out and upgrade to more money dac's. Hate to say it but my turntable is not being used like it use to. 
One thing I would highly recommend would be to use a linear power supply (you'll need an interface avaialble online). Significantly improves the sound. Bigger soundstage,  better low end, better high end. Ended up being around $500. Totally worth it IMHO.
Just an FYI, on the subject of the Node 2i and sorry if it's already been brought up.
The BluOS update (3.14.5) this month added support for Radio Paradise, the first internet radio station to stream in MQA. They have 4 MQA stations and 4 CD quality versions of those stations. 
It's radio, so you get what they send, but it's a free way to sample MQA if you don't have it already.
