I have built 4 of these to date, the first was for me but as soon al local Las Vegas audiophiles heard it they were begging me to build them one.There is another reference board in the design stages as I have been in direct contact with Rick Reigel from GaN.
As far as any tests done my AS, remember the design was built to show off the performance without high loop feedback which is what we want, trust me. The board has the ability to have open loop and closed loop feedback and the closed loop sounds a lot like my FM711 where the open loop is just another world of clarity, tone, timbre and low level details and spacial ques that are wiped out by SS designs. I have them heatsinked especially since my 2 main speakers, Apogee Divas and Thiel CS5i's are mean speakers to drive. The GaN amps are the future of amplification, trust me, you will be seeing a lot more of these amps. They remind me of super powerful VT25 amps for medium to low efficiency speakers.
