Id class D ready to take on the $20K amps?

Yes
The only way class D amps don't compete with one of those is in bandwidth, they quite reasonably don't go up to 600khz. Otherwise most Hypex and all Purifi models beat them.
I guess if you are looking for fancy gold-plated enclosures and stuff, most Class D products have a ways to go, but in sheer performance they're equal or better. I will bet however much money you care to wager that they'd come out the same in ABX tests with the vast (VAST) majority of speakers.

Take on a basic voltage regulator with 1% THD? Modern class D amps would fold that device 7 times over and put it in your pocket.

That was a few years ago. Currently Bruno is pushing the state of the art.
New Purifi amplifiers coming
At the High End I met Purifi, and I was offered a sneak peek of the new 1ET9040BA. Available soon-ish, this amplifier module is a full bridge topology (a first for Bruno Putzeys?) and it has a residual noise of 8uV, so it beats the newest NCorex's. As for power and stability, if I understood...

Until they are sold with a snake-oil fill, they can't compete.
Isn't McIntosh offering a class D now?
This question is about two decades out of date…

Yeah. Another class D thread.
This is surely a troll tread 
dar-t-zeal is good bait extremely expensive snake oil products with awful performance in many aspects .
Any decently designed amps beat those does not need to be class-D at all .
The performance curve seems to turn after some price point and you get into weird high end territory.
A normal honestly designed amp , designed with engineering and science in mind beats high end all the time.
for that money a go Accuphase if I wanted expensive electronic sculptures that also are amplifiers and had 20k $ to burn
I see myself out of the tread .....

The cabinets aren't the same and they are missing enjoyment and pleasure dials. But the hypex and purifi offerings have more linear FR, less distortion, and are far more energy efficient. So for fidelity sound reproduction, they are a better choice.
Those amps are a joke:

Sure, they may not be good at electronics. But they know how to charge a lot.Those amps are a joke:

Class D amps cannot compete at all in weight, frivolous looks, expense and size. Of course, those things are important. Essential. Believe me when I tell you.

My Class D integrated has the weight, frivolous looks (maybe), size and a chunk of the expense. Of course, anyone owning a $20k amp is going to dismiss it despite those things.Class D amps cannot compete at all in weight, frivolous looks, expense and size. Of course, those things are important.

It's a marketing question.
People do not buy 20k amps because they really sound better but because they are snobs that buy believes and stories.
As long as Class D is being misinterpreted as digital amplification (which it isn't) and by many regarded as sounding 'clinical' it will be difficult.
High-end audio is not about technology but all about believes, story-telling and lack of masculinity that seeks for compensation.
