Curious to know your streaming and dac set up and the best recommended streamer under $15k


Curious to know your streaming and dac set up as well your best recommended streamer. I have recently upgraded my dac and have used 2 different set ups in an attempt to find the my best combination.  Former set up was Roon Nucleus+ connected to a Lumin T2. New set up is a new Nagra Tube Dac and a separate Power Supply and I had that directly connected to my Roon via Shunyata Sigma USB cable and using a Shunyata Ethernet connection to my network. Didn’t feel like that was my best possible sound so introduced the Lumin T2 back into the fold as my streamer and then connected the Nagra to the Lumin T2. This was a much improved sound. At this early testing point I’m curious to see if anyone uses and/or recommends a streamer that has significantly improved their sound under $15k. I would like to stay with the Roon platform. 
 

Current set up is Audio Research Ref160S amp, Audio Research Ref6SE pre-amp with Wilson Alexia speakers.  All cabling between these components is Transparent Reference. 
 

Unfortunately, I have not had time to photograph and upload my new Nagra dac. 
 

I really appreciate anyone who takes time to assist with some thoughtful ideas, experiences, or recommendations.

@woots : I appreciate you taking your time to explain your process. It all makes sense.

Here are my thoughts, with the assumption that your Nagra DAC is there to stay, and you keep Roon (I am a 5+ years lifetime Roon subscriber, so I understand). There are two ways to do this:

1) Keep your Nucleus as your remote Roon Server / Core. Get a standalone Roon Ready streamer (no DAC) to “feed” your DAC (I.e Streamer —> USB out —> DAC). Such as the LUMIN U1x. Plenty of good options on standalone Roon Ready streamers/ network transports, but since you like LUMIN sound signature, U1x

 

2) Get a very good Roon Core / streamer unit (ditch Nucleus), such as Innuos Statement or Zenith MK3 mentioned above. Run USB out from it to your DAC. Yes, Innuos has relatively low powered processor (on purpose, by design), but unless your are doing heavy DSP on Roon, or you have a huge library, it won’t be a problem. With Innuos, in addition to Roon, you can also use their own Sense streaming platform, and you can switch between Roon and Sense with a tap in your tablet or phone in no time

+1 @jimmy2615 the Lumin U1 is supposed to be an awesome unit if you have a DAC. It’s basically an S1 without a DAC. I’m wrestling with this decision right now. It’s is highly recommend by a friend of mine who who’d did some comparisons with others in the Lumin line including the X1. This is one serious streamer. My 2 cents. 

@designsfx I didn’t know a Lumin U2 has been released yet? Do you mean the U2 mini. Also a great unit. I’m currently in the process of deciding on the U2 mini or the U1 or wait until a U2 is released. Thanks. 

@woots  - If you haven't done so already, maybe circle over to WhatsBestForum ,it's quite possible that you may find some folks with either your model of Nagra DAC or one of their other models and who also stream.
