I'm looking for a DAC and I would probably get the "Okto dac8 Stereo D/A Processor", but they have -- unfortunately -- stopped taking new orders for it (for now).

https://www.audiosciencereview.com/forum/index.php?threads/okto-dac8-stereo-dac-review.14705/ I enjoyed the sound of
the SMSL M400. (I had a unit with defective Bluetooth, so I returned
it.) I could order another one, but I really wanted the Okto dac8 stereo, even though I haven't heard it. I like it in part because of the connections and other features, and I expect it to sound good.
If anyone has heard the Okto and the SMSL M400, how do they compare?
