I have looked over that Technics technology and hope that it may trickle down into more affordable components as right now 20k is a very hard sell to non believers.
It like everything in technology life it will come to the masses. Just look at all the Formula 1 improvements that all come to your family car within a very short time.
Hopefully somebody can make it happen for a lot less dollar!It will, those same EPC guys who made the GAN transistors for that Technics SE-R1, were also the inventors of the "power mosfet" many years ago.
They are the inventors (Formula 1 guys) and they sell their inventions to the big semiconductor manufacturers, who then stamp them out by the thousands, and supply them to the masses.
