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.

@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.

I purchased a Baetis Revolution

And am quite happy with my digital front end now.

Customer service is outstanding

So in reading back through this I think @jerryg123 has hit the nail- ROON

I don’t understand the benefits of Roon as I haven’t used it. I use a Naim Uniti Core for ripping/storage because I prefer the sound of its playback through my Dac. Its library management/app is really good- the sound is great.

@dinov - Yes, my transport is a U2 Mini. I’m just now experimenting with streaming and wasn’t sure that making my first investment into a higher priced streamer would be wise in case I didn’t care for it. I also didn’t want my impressions to be muddied by the influence of a different Dac. The U2 was the better option for the test.
Honestly I’ve enjoyed it so far but when I A/B streaming 24/96 FLAC (Qobuz) against my digital files through the Naim the Naim wins every time. The Naim playback is not as “bright” as the Lumin yet still produces a fuller more detailed reproduction. 
@yyzsantabarbara  In reading your response it sounds like you may also prefer the Lumin in the capacity of a transport through a great Dac better than an all in one (unless I read that incorrectly). If true this further galvanizes my belief that separates are still the better option (for me) as opposed to an expensive one box solution.

@woots  Where is Roon falling into play here? When you tried the Innuos did ripping CD’s play into that? 

It sounds like the Roon interface might be the center to which all things orbit, but without the user experience I’m having trouble seeing it’s value as other products have great interfaces as well. Unless of course Roon offers something that enhances sound quality but that isn’t my understanding of its purpose.
