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!

1 - stick to replacing the marantz with a proper preamp
2 - be careful when posters with a grand total of 2 posts tell you you should buy a $4000 digital appendage like an m scaler (don't get me wrong... a m scaler is a good piece, i have one, but it should not be your priority... not even close...)

Appreciate the follow-up - what preamp thoughts do you have?

I took his comment to mean, forget about MQA support in your system, try this upscaler instead.
I would try cable upgrades.  Best I could afford. At this stage I believe the bang for the buck would be much higher than component upgrades. AC cables first. 

 Further, the biggest upgrade ever in my system was CS2 footers.  Not sure if these can be had on a trial basis. 

Best of luck, and enjoy the chase.

1- Good Tube Preamp definitely. It will be significant upgrade in SQ. Modwright LS-100, Modwright LS-36.5, BAT, or Cary Audio could be in your price range. 2 - Node 2i is entry level streamer. You could upgrade it with some thing like Lumin U1 Mini which is transport streamer so you could use it with your existing DAC or maybe Lumin D2, Teac NT-505 with MQA DAC on board will be upgrade to.  3 - If used staff acceptable you could upgrade both options. It not go with new tube preamp.
