I have Q5S+AM3D with 660S. No need AM5, but I tried with that, and served more power. My opinion: Not enough max volume when I used as soundcard on Windows 10, I don't know why.
But! Enough power when use with Tidal (on Windows 10) Passthrough MQA Encoding (software decoding off) is ON and Exclusive mode is ON.
Enough power with iPhone (cable connection) too.
You can pump up a bit with a boost button (I didn't realize decreased quality when I used).
@FiiO should enhance the Windows 10 max volume on next driver update. For example, they can put a slider with + x decibels or so.
I have Apogee Groove, I had Mojo both was much louder on Windows 10.
660 are 150 ohms so bit easier to drive than 650/6xx which are 300 ohms.
But Ill try the balanced output as suggested by cevisi before going with the am5.
