I don't know if you are asking about the class D audio or the AGD......but I emailed Tom at Class D audio a week ago and here is the latest info on class D audio GaN amps:
The $1600 amp is going through a revision (release time unknown). There is a $700 GaN amp that will soon be released. Just finishing the powder coating now.....then to silk screening....then to final testing and then shipping. It will be 150 watts a channel, 100K input impedance, 3 position gain, balanced and unbalanced inputs and uses a switching power supply to keep the cost and size down. It is 10 inches wide and 2 inches tall. Will be the cheapest GaN amp available. Should be fun.
