Hello,
I also use the Innuos Zen Mini Mk3 as a streamer running Sense via USB into my T+A Dac200 then into my Krell gear. I am quite happy with this chain, but I am considering changing from USB to I2S just to see if/how it is different. My prior DAC was the Audio Mirror Tubadour III SE, but I found that too soft. I also tried the Krell DAC, which I liked, but it was missing what I describe as energy. The worst DAC I tried was the internal one in the Innuos Zen Minik Mk3 - but I ran that with Roon.
As previously suggested, just try a few and listen to what happens. If you can’t or don’t want to buy new with a return policy, you might try used as you should be able to resell it for what you paid for it.
Good luck.
