I played Tidal (lossless) over aptx to M1 to Mojo and it sounds very good. Sounds better than Apple Music directly to Mojo (Which also is very good). I'm not they guy who says they all sound the same. I can tell the difference right away between formats. Because I spends alot of time with mojo, cans, and same track.
For the price I don't think you can go wrong with M1. It's a good backup DAC for PC, does bluetooth transport, also have my microSD loaded with my lossless.
Once a good case is made for Mojo and M1 it would be very small footprint as well not as long as Poly. Right now I'm strapped and its nice size.
When you pair M1 to smartphone via Bluetooth, did you play Tidal from USB Audio Player pro app or directly from Tidal app?
I don't know what that app is. Just standard Tidal app Apple App Store.
