Help with DAC and Streamer suggestions

I hope everyone is staying safe and healthy and spending lots of time listening to great music!

Before I ask for your advice, I thought it would be good to tell you my system:

• Martin Logan Summit X speakers connected with Acoustic Zen Hologram II speaker cables.
• Shiit Yggy DAC connected with Acoustic Zen Matrix II reference interconnect.
  
• Bryston BDP-1 music player connected with Kimber Kable D-60 digital cable.
• Oppo 105D for SACDs, modified by Ric Shultz connected with Toto Tungsten interconnects.
• Prima Luna Dialogue HP integrated amp with original tubes.
• Furman Elite 20 power conditioner.
• I have a dedicated 20 amp line running to all audio electronics.
• All electronics are connected with Pangea power cords.
• All music passes through Roon on my computer, and while playing music the computer does nothing else.  The computer has a direct connection to the internet, and all music is sent to the streamer via Cat-7 cable.
• I listen to Tidal primarily, along with some of my own FLAC files.

 I want to change my music streamer and DAC.  I'd like something that will make the 2nd unfold of MQA, but that's not a deal killer.  I have around $6,000 to spend, and I'm fine with used equipment from Audiogon.

Here is what I've been considering:

• Primaluna EVO DAC - $3,000, not MQA, won't add a better streamer, but might sound great with my Primaluna integrated.
• Aurender A10 streamer/DAC combo - $5500 new, will make the MQA unfold.  Not sure about combining the streamer and DAC.
• Mytek Manhattan II DAC with network card - $4700 new, does not add a better streamer.
• Roon Nucleus Plus streamer ($2500) and perhaps a better DAC.
• Small Green Computer Sonictransporter I5 for Roon and music ($1075) and better DAC.
• Keep the Bryston and buy a Holo Audio May DAC ($5,000).
• Certainly open to other suggestions.

As you can see, lots of options to choose.  :( 

I live in a very small town in Central Oregon and can't audition different components.

 I'd love to hear your suggested changes for my DAC and streamer!

Thank you!

Steve
