I agree about tubes, which are like fixed tone controls in comparison to linear behavior of modern class D.
I have no issue with your choice of output devices. I also designed a heatsink before, years ago, so not one is going to "instruct" me on thermal behavior of devices. My HYPEX NC-400's don't have heatsinks, and don't use GaN transistors.
If someone else here wants to do further name dropping, I have Carver Mead's Cell phone number, since I worked with him 26 years ago. His knowledge goes way beyond all this Audio stuff, and is responsible for much of modern electronics technology.
So now that you admit you have a selling interest in an Amp whose devices you claim are not that expensive, $30, that means $300 for each device when marked up to the consumer level inside a product. Do you use more than oner per amp? LOL.
I measured 124 db output in my living room in my Jubes with $40 TI chip amps and a 19 volt, $10 Laptop power supply, 6 years ago. That was good enough for me.
Good luck with your sale.
