Streamers/DACs for Hi Res Streaming

Long time listener, first time caller. I am looking to upgrade my streamer/DAC from my current Cambridge CXN v1 in 2020 to take advantage of high res streaming. I had settled on shopping for DACs that include full MQA decoding, because I love what I hear from Tidal Masters even from my Dragonfly Red on my modest office system. But now that Amazon has added high res streaming, I’ve given it a try and am very impressed with the sound and the depth of catalog. (Qobuz only seemed to have 2/3 of the music in my library.) I understand some don’t like MQA because it requires filter settings that somehow are suboptimal for non-MQA playback, so streaming flac files has some appeal to avoid any limitations. I would like to get a dedicated device so I’m not streaming via my MacBook.

So, my questions are:
1. What are people’s thoughts on whether using an MQA compatible DAC significantly compromises its playback of non-MQA files? Is this an important issue weighing against Tidal Masters?
2. Are there any updates on audiophile manufacturers integrating Amazon music into their devices, so they can stream directly from the internet (not via airplay from the phone)? I only see that they are "looking at it."
3. Any specific thoughts on the Mytec Brooklyn Bridge vs. Cary Audio DMS-600 vs. Aurender A10 vs. Bryston BDP-3.14?

Sorry for the compound questions. Thanks in advance for your guidance.
