GaN FET-based Class D amps

Can we get a running list of available (and soon-to-be available) GaN-based Class D amps?

I have PS Audio M700 monoblocks and am looking to upgrade!
1: Technics- SE-R1
2: "           "  SU-G30
3: Merrill Element 118
4: "                    "   116
5: AGD Production GaN Tube. 
6: Class D Audio (said they were prototyping)
