My lyngdorf SDAi2175 has this, and is a class-D design.
All digital baby, with volume going up in 0.1 steps from 0-100, with my ATCs really only putting out sound from 40 onwards. Beast of an amp, although it defaults to 0 when powered off at the plug which is annoying having to crank it all up again.
Solution: Live at homewith parents and leave on standby
