Next Best Upgrade for Tidal MQA?


I’m trying to decide what my next best upgrade is going to be to improve my streaming music quality (predominantly Tidal, and Tidal MQA, when available).

Current setup:
KEF R11
Custom Deep Sea Sound 18” subs (2)
Marantz SR7012 AVR
Bluesound Node 2i
MyTek Liberty DAC
Parasound A21+

I’m wondering if I’ll get a bigger jump from inserting a Parasound JC2 BP as a pre-amp or replacing the DAC/Streamer with a MyTek Brooklyn Bridge? Or is there something else out there in the $2500-4000 range that will help make a significant jump?

Help and thoughts appreciated!

@richdirector  I have it connected via optical right now and the passthrough is enabled so that the internal DAC in the Node 2i is bypassed.  My MyTek Liberty DAC is MQA-certified.  Regardless, I have read elsewhere that the Note 2i will still only pass through at 96khz.

@paulcreed   Thanks for the suggestions.

@snackeyp  Thanks for the suggestions, although I struggle to believe that the streamer is the single, next-best, upgrade versus the Pre-amp.  As of now, all the Node 2i does is act as a digital source, it is not doing the digital-to-analog conversion.  
@bruxesq Don't rule out the streamer.  The quality of the source with digital is huge.  The DAC is also hugely important.  Cheers
I don't know if this has been mentioned but John Darko posted this over at his site:https://darko.audio/2020/10/tidal-connect-who-what-why/

It goes into relating how Tidal is now going to operate like Spotify Connect and all the manufacturers that will or do carry it.

All the best,

Cary Audio DMS-600 DAC/Streamer. Great sound and great reviews. I hope you can find one
