Bluesound node confusion


I was hoping to get some help determining the differences between the different versions of the node. First gen .,second gen., 2i in between, n 130,n132?

have a second system with some klipsch rp600m II an old outlaw pre/pro and would like to stream on the cheap. Using a slash 6 and my phone with iTunes and it’s pretty rough sounding in the front end. I’ve never had a dedicated streamer and thought this would be a good way to get my feet wet.

Any advice will be greatly appreciated!

Had the 2i and didnt like it. Had an opportunity to get the N130 with upgraded power supply and its fantastic. Running it straight, no DAC. Added bonus is it can run Dirac room correction software. 

here's my question, I have a Bluesound Vault hooked up to my main stereo. want to be able to play this in sink with my new patio speakers running on a separate system. I tried using Y connecters from the bluesound to each system, get a ground loop issue. I could try removing the ground from one system, but also could get a Bluesound Node that would sync, am I correct? 

Also, I believe that from N130 (Node 2021) forward, USB 2.0 available as output.  This can be a big deal if your outboard DAC prefers USB over SPDIF or Toslink.

Dirac correction is probably worth it to me. Internal dad should be fine for the level of system I’m running it in. Thanks everyone for the input!
