Hi Guys
Nothing to apologise for!
Class-D amps and SMPS share the same appeal of small size and light weight, but also share the same disadvantages compared to pure linear inasmuch as linear deals with load surges and variable loads much better. The output filter for a class-D amp is optimised for one load value where a linear amp can deal with a varying load with much less variation of THD. Similarly, SMPS can handle fixed loads where linear will allow surges at startup, say for tube heaters.
