New DAC! Meitner MA3, Denafrips Terminator Plus, Holo May KTE, Mola Mola Tambaqui

The i2s does not mean it can decode DSD (SACD). I do not think that is even allowed with the licensing terms of DSD from Sony. 

My prior Mustec 005 DAC had i2s and that had nothing to do with DSD. i2s is usually a little closer to the DAC convertor (maybe chip, FPGA, etc) over another input such as USB. It could be a shorter path to the DAC's internals.

Why not look at a top end SACD player that now have DAC inputs such as USB. The Esoteric XD lineup, Luxman, Playback Designs, Marantz, etc

SACD is a low priority.  Just seemed like more companies are starting to support i2s so I assumed if you get a DAC with this it's a little more future proofing. 

I highly you suggest checking out the exceptional T+A 200 dac Myself and many others in our north east club have tried all you mentioned and many others .

the T+A is around $7k  and I know 4 guys that bought it vs Anything under $15k 

I am buying one for my early 🎅 Xmas present it is that good very natural sound  and great detail but not in your face like the Dave dac Balance is the best word 

and has many of options even HQ player built in and meters are very good., checkout the reviews first then arrange a audition.

I love my Tambaqui but have not heard any of your contenders except Dave.

Add Bricasti to your list. With an optional network card it’s Roon ready. All you need is your mac mini as roon core and ethernet cable connecting the Bricasti to your network. Clean set up (no streamer needed) and great sound. Pick the model within your price range.
