If it walks like a duck and sounds like a duck, it is probably a duck.
From Wiki;
Class-D amplifiers work by generating a train of rectangular pulses of fixed amplitude but varying width and separation, or varying number per unit time, representing the amplitude variations of the analog audio input signal. The modulator clock can synchronize with an incoming digital audio signal, thus removing the necessity to convert the signal to analog. The output of the modulator is then used to gate the output transistors on and off alternately. Great care is taken to ensure that the pair of transistors are never allowed to conduct together, as this would cause a short circuit between the supply rails through the transistors.
So yes, Class D is more accurately referred to as a "switching amplifier" rather than a "digital amplifier" but things get blurred when binary quantization is involved as binary quantization is at the heart of digital too.
I find it interesting that in order to "cut me down to size" you chose to seize upon my bad choice of nomenclature (when I in fact used BOTH within the same paragraph!) rather than comment upon the bigger points made in my post.
I will say it again also-I have no doubt that this is a very fine sounding amp. I would expect nothing less from a man of your immense experience, intellect, and knowledge. I just get my hackles up a bit when someone like our OP posts a sensationalistic thread title and then waxes on and on. You don't want to be equated with Tekton do you?
