Do ClassDAudio Amps Have Proper Decay Of Notes?

While I've seen graphs that dramatize a digital waveform I honestly can't hear anything that would suggest a stair stepped waveform or "digital noise" from any of the switching amplifiers I've listened to

Yes as Ralph has corrected about class D classification not being digital.

Also the "digital noise" I believe is an analog switching noise and is around 600-800khz, too low to be effectively completely filtered out of the audio band without effecting it with early hf roll off.

The new Technics SE-R1 with their new proprietary transistors takes this switching noise up to 1.5mhz which is a step in the right direction.

But from those in the know the switching noise needs to be up around 3-5mhz to make the filtering completely effective, and not to intrude into the >audio band at all, then it will take Class D into proper hi-end amplification.

That’s when I’ll sell my hot inefficient heavy boat anchors and also go Class D, and the smart linear amp manufactures will have their fingers on the "sell my business button" before this this technology comes along for anyone to source these new super fast transistors, or compete with the Chinese.
