Ok, I finally found these guys. Not an easy find. I totally understand R&D cost, etc., etc. But if these guys are offering GanFET amplifiers under $1000, and none over $2000 then why are these others, equally new or less known companies charging $5k - $10k?
It almost seems like there must be OEM GanFET modules now available. Or is it similar to Purifi Class D, where manufactures could purchase modules or the technology and design their own versions, such as what T+A did.
To give a complete answer would require a deep dive and from someone more technically minded. I have learned that like any amp it's the sum of the parts not just one, like a module etc. I've also learned as in class A/B, class D needs a good power supply. A light weight switching power supply will make the amp less robust. The power supply is why some class D with same power rating can't compete with class A/B. Class D always looks good on paper but some fall short in real life. Usually it's the cheaper variety where costs had to be cut somewhere. Class D will still measure well with a not so adequate power supply. Another area is clipping, Some class D will compress when running out of steam or power supply stresses yet they will still show good distortion measurements.
