GaN has been getting HUGE in the audio realm, less so in western companies but in Asia in the PA realm its been the go-to for a few years now. Admarks AD442(4x4200w @8ohm) and AD60(2x6000w @ 8ohm) are a great example.

1U, Compact and more power than you can poke a stick at and fairly reliable. Also their pricing dumps on the offerings in the west (Both well under $2000 AUD). Just be warned you want MINIMUM 240v 15A or 32A single phase power circuits for these and probably run them at 1/4 or 1/8th rated output for ultra low THD.

Yeah, it's definitely coming via the Chinese companies, and Korean as well (HiFi Rose), and everywhere from budget to expensive. Class D amps have been making headway against traditional scepticism for a while now, and GaN switching performance is pushing that even harder.

Peachtree seem to be one of the US companies pushing GaN in a big way, including their pure-digital amps.
