I encourage everyone to listen for yourselves.
While there are lots of fun puzzles left in the world of audio technology, solving them may or may not have appreciable benefit to end listeners.
That’s something only listening for yourself can decide.
Selling you a problem you didn’t have in the first place is what drives the industry.
The trouble with the Techniques amps is that you can't attribute their sound just to 1 technology. This is a pretty remarkable amp, but there's also DSP speaker impedance correction going on. You cannot say "great amp, must be the super fast switching speeds" unless you can eliminate other variables.
Are fast transistors cool? Of course they are. But great Class D amps have been around for ages.
Yet here is George, standing outside an airport with a sign saying "Planes can't fly!"
