GaN amplifier from GaN themselves limited supply!!!

The first mentioned history of the new GaN output devices here on Audiogon

The new GaN transistors were reported here some 4-5years ago about how they will transform Class-D, especially the way Technics used them with the SE-R1 and it’s 1.5mhz switching speed instead of what everyone else uses around 500-600khz.

Here are the first post on Audiogon mentioning the new GaN transistors from "Alex Lidow" of EPC who was the inventor of the Mosfet, or one of them.

And the video he uses and measures the original older GaN by GaN evo board this thread is about the newer model.

And dht4me who has been in direct contact with Rick Reigel from GaN, says there is another "Reference Board" in the design stages.

This present unit bodes very well for the members here who can do very simple kit assembly themselves, basically mount the GaN board it in a box add some rca sockets and speaker terminals.

You got a killer Class-D GaN integrated amp with dac!! and variable feedback for well under $1500 that "could" blow any others here away, as dht4me reported when he demoed it to the LA audio crew and said,
"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."

@dht4me

Do you know what the RCA input impedance of this board is, as I've looked and can't find it anywhere, maybe Rick Reigel could let you know if you don't?

Here we have the video on the $1300 Gan by Gan Class-D and Power supply, fully loaded with a dac, volume control, switchable inputs two digital and two analog and variable feedback (closed loop/open loop) this is plug and play almost, all you need is a box.

44th minute onward shows you how to use the feedback control in real time while listening to pick the right amout to suit your liking, so listening comparisons can be made. And as I said it also the Scamp connection which also gives many DSP control values to be had via you laptop.

There is is the development stage another one from GaN which they call the Reference board which sounds to me like it could be even better? That could take a while though.
