any suggestions on what to replace Bluesound Node 2i with


I am doing a major upgrade on my home theater system. I want to upgrade my streamer. I can spend around $4500 if I have to. My dealer played a Lumin T2 and the music, Tidal, sounded amazing. He said I would be okay with the D2 if I wanted to save money
Any one have any experience with the the Lumin's. I am open to other streamers, it does not have to be Lumin. Thanks

Sounds like a great dealership. I’m assuming (should never I know) the dealership let you take the Lumin home in your system so you’re truly hearing only the difference between your Node 2i and not their system?

Are you using a separate DAC, and if so what are you using, including cables and type?
I just read this great response on another forum from a person that is an audio reviewer. 

---------------------------------
I've used a few streamers in my time as a reviewer and the ones I recommend at each price tier are:

1. Bluesound Node 2i ($550)
2. Innuos Zen Mini ($1400)
3. Innuos Zen MK3 ($2850)
4. Metronome DSS ($4200)

You really do get a performance jump in these, especially once you get to units that have real power supplies in them. I used the Pontus ii for my Metronome DSS review and I thought the two worked well together. If I were spending my own money though I would probably get an Innuos. With the Zen mini you do have the option to upgrade to a separate power supply ($700) down the road.

I haven't heard these side by side, but detail and control are the things I've noticed most when I got up the streamer chain. The Metronome is a detail machine, and it has whisper quiet backgrounds, reminded me a lot of their CD player which was far and away the best digital source I have ever used. The Innuos stuff I got to play with for a few days only, but I remember they had a lot more "body" and low end than the Node 2i which I have heard in a number of systems. I think you'd be happy with either the Zen Mini or the Zen MK3, they will sound a lot better than the normal $500 wall-wart streamers. Also they let you rip your CD collection so you have everything in one place. I would find a dealer to see if you can compare the two streamers, they might even let you bring in your DAC.
Thanks for the responses. I have the option of streaming from the Node 2i connected to Anthem 1120 with optical. I also stream to my 1120 with Control4 if you are familiar with that which is a hdmi connection.  I also stream Apple Music sometimes from my Apple TV which is connected with HDMI 
I am not familiar with the streamers mentioned but I will look them up
While you are doing research check out Wolf Audio.  I currently use their Alpha 3SX but the new Luna is close in abilities and performance.  Customer support is excellent.
