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:
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!

Innuos zen mini mk3 w LPS as Roon Endpoint
Network Acoustics ENO filter
IsoRegen with USB adaptor
Small Green Computer Sonic Transporter i5 for Roon core
Throw in some good USB and Ethernet cables and LPS for Isoregen & Sonic Transporter

Appreciate the suggestions. However, the Innuos Zen Mini is really overkill for my situation. I have no need for a CD ripper or onboard storage. I also have no need for Roon as long as the network streamer can stream Tidal directly. Seems like I would be paying for a lot of features I won’t use and have no present interest in getting into.

Again, I pretty much exclusively stream Tidal (and Tidal MQA when available). I have no digital or physical media collection whatsoever, other than some legacy SACD/DVD-A (that I may sometime deal with later through my Oppo 203).

If the network streamer is the single next best upgrade, I need to find one that is more focused on what I do.
@bruxesq here's a perhaps slightly out of the box possibility. Check out the Lyngdorf TDAI-1120. That will give you an integrated amp with home theater bypass, streaming, and room correction all in one device for about $2k. You could biamp your speakers by running the preout to your Parasound and sell the Node and DAC.

Thanks for the suggestion.  Given that the TDAI-1120 would replace my DAC, Streamer, and 2 channel Amp (and I could sell all 3 to mitigate costs) - I started researching the TDAI-3400 (the bigger bigger brother in the series).  Found interesting comments by the OP in this thread:

OP said he moved on to a MyTek Manhattan II DAC after living with the Lyngdorf for a year. His quote was that the upgrade in sound to the MyTek was “profound” and that a stand alone streamer sounded better.  That gives me a lot of pause.
@bruxesq That Mytek DAC is $6k on its own so not even close to a valid comparison against an integrated amp / DAC / streamer / room correction device for $6,500, much less the $2k TDAI-1120. And the room correction, depending on your space, could make a much bigger difference than the DAC. To top it off, that guy you’re talking about ONLY used the Lyngdorf as a DAC. That’s like buying a BMW to use as a heater for your garage. Of course the Manhattan sounded better. What streamer, preamp, and amp was that guy using? I bet they cost more than the $500 price difference between the Manhattan DAC and the Lyngdorf that does it all but was (crazily) used only as a DAC.
I haven’t tried the Manhattan to compare but I’ve got the 3400 and I find it to be absolutely amazing. It’s probably the only technologically advanced device I own that just works all the time and does everything I need. It also sounds incredible and puts out 200w into 8 ohms or 400 into 4 ohms. If you went with the 3400 you could also sell your Parasound...
