BTW: that "future" much higher switching frequency I talked about above, is closer than we think.
Technics with their SE-R1 are showing vision by developing their own much fast switching frequency transistors, double the norm that’s around now. It would still be better if it were 5 to 10 times faster, but it’s small steps to a good end for Class D. Then you’ll see me sell my big hot power hungry boat anchors.
But the amp is expensive at around $22,000.00usd I believe.

And you can bet they’re not going to sell those transistors to just anybody.
Just one reviewers words of what he heard:
"Listening to tracks that we’ve heard 100s of times — and on excellent systems at that — is now a revelation of once hidden nuance and detail. Not only are we hearing things we’d never heard before, we’re hearing it in a way we’ve never heard it before. A music system that sounds like a live performance is a tough goal to attain, but Technics’ flagship nails it."
