i never tried them, but i was interested when they were first released. i'm not sure but i think i remember reading that the devices were prone to latch-up problems. naturally, that wouldn't go well over well for building a quality, reliable power amp. i think nelson pass released a product using them years ago ; maybe he will comment ....
good luck,

Afaig, the front end input of the first IGBT amp was by Papa's hand, while he was still at Threshold, but everything behind it was Michael Bladelius' .....doing.
