There's nothing special about 200mA of current into 32ohms as other manufacturers seem to be able to that in full Class-A with no overheating issues.I didn’t say that ‘other Class-A amps do not get hot’. Please don’t misquote me. I know perfectly well what I meant. Also the Chord Mojo 2 does not clip above 3V and it’s SINAD has been measured best between 3v and 4v. https://www.audiosciencereview.com/...hord-mojo-2-review-portable-dac-hp-amp.34160/
Not sure if it uses 200ma or less but if you're worried about overheating maybe you should look elsewhere than the Xduoo TA-22..
And yes I know about that review of the Chord Mojo 2 but I find it sounds better in lower voltages - the blue color which I see now is even lower (1.5V). I find that the sound becomes a bit harsh above 3V and that it starts to clip during louder passages. At maximum voltage it's unusable.
