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

Why not keep the node and upgrade the delivery to it and then upgrade to external DAC.
start with small green computer solutions. They have fiber optic options that clean up the signal to the streamer. Never spend more then you have to. Enjoy the music.
@jjss49 Yes, as my post stated I am looking for a replacement. I find myself listening to Qobuz more through my Control4 Hdmi set up with my Anthem 1120 than using the Bluesound which is connected optically to my Anthem. I did hear the Lumin and was pretty amazed, I just don't want to spend a lot of money without checking other options
When it’s digital it is not hard to make something sound different as desired . So no doubt streamers can sound different for many reasons. Outboard DSP is likely to be able to reproduce similar results.
I think it’s better to say I have never heard bad sound come from a streamer through a good DAC, not that they all sound exactly the same.   
Have you tried a different connection than optical with the Bluesound?   That alone might make a difference.
