In the case of your Ayre amps, [their specs] show 120 watts power consumption with no signal

 

Likewise, to compare the heat generated by a digital (or any other) amp, simply look at its specs for power consumption at idle and at higher power output.  The idle power consumption is more important unless you listen to extremely loud music.
