So, I bought a Chord Hugo TT2...now what?

The Vault is very good .  It was my first streamer.   I replaced it with an Aurender N200 and that is a great unit.  

I still use the Vault in a second system.  I actually was able to copy the Vault's files over the network and put them on the N200's SSD drive. I still use it to rip and use it every day.  

You have a great system that would definitely exploit a better streamer.  Not that a Vault is bad,  but something like an Aurender or Innuos would be a good match with your other gear. 

I have Aurender N200 driving TT2 via Audioquest Diamond USB cable. 
Actually a really good DAC once you dial in the settings. I’m selling mine by the way….you could have saved couple of bucks…

Congratulations, I traded in a Cutest about a year ago on the TT2 as well. I also am using a Bluesound Node and am using a Kimber D60 digital cable. I would like to upgrade my streamer before I would add the M Scaler. My dealer has agreed to set an A-B with/without so I can hear the difference.  But as with most people these day, money is sand in the gears of making these changes. 
But again, I am happy for you, I can’t imagine you not enjoying your new DAC. Personally I would get used to it before adding the M Scaler, which I want to hear before I put it on the radar screen. One thought is maybe down the road I’d buy a Dave which the coupled price of the Hugo and the M Scaler are on the outskirts of that same neighborhood. 
 

Let us know how you like your Chord

I purchased a TT2 about six months ago, and my next upgrade was the LTA MZ3, which I primarily use with my Focal Utopia headphone. For me, the TT2 already provided a significant boost in resolution, so I didn't rush into getting an M-Scaler. I might consider it in sometimes this year of next year. In the meantime, I am enjoying the synergy between the TT2 and MZ3. The TT2 delivers very good resolution for me at the moment, while the MZ3 adds a bit of that "tube magic" without the usual heat and lengthy warm-up times—just 15 seconds to get up and running, which is incredibly convenient for a tube amp.

Regarding streamers, I'm currently using Audirvana on a Mac, connected to the TT2 via a Tubulus Concentus USB cable. I had planned to upgrade my streamer next, but I'm holding out for more options with Audirvana Ready support. I prefer to stick with Audirvana because I appreciate its EQ capabilities via plugins. For instance, I usually add a low-frequency shelf filter of 3dB when using the Utopia directly with the TT2, and with the MZ3, I often boost the lows further with an extra 1dB or more.

So, if you're considering your next move, think about what will enhance your listening experience based on your current setup and preferences. For me, the MZ3 has been a great addition. I’m not in a rush to rapidly upgrade my system anymore. I’m content with what I have and happy to enjoy it until I feel the need or the want for further improvements.

That’s a nice system! Underserved by the Node I think. As others have said, let it settle in for a bit. Clocking and noise are key factors with digital. If you are using coax, the Node is providing the clock, which is not ideal. If you are using USB the DAC is providing the clock. Try both once things settle. Good digital cables make a huge difference. I just upgraded my USB cable and experienced a huge improvement in clarity and soundstage.
