GaN amplifier from GaN themselves limited supply!!!


There is this integrated GaN , made by GaN themselves, so you know it "should" be good.
(Could very well be the best of all GaN amps)
(single purchase only, not available for multi purchase for commercial Class-D manufactures)

But you’ll have to put it in a box, comes with all you need, the amp and power supply, and dac??!!!
(if you can build simple kits you can build this, would it quite simple to make up)
.
You have with it:
Volume control
3 x switchable inputs
2 x Analog stereo inputs rca & jack
2 x digital spdif inputs, optical and coax (yes it has a dac in it too)
And this is neat, user variable negative feedback!!! for those that don’t like too much for the sake of "better" measurements" and want a more organic sound, all for just $1.3K

Amirm’s conclusion:
Conclusions
MOSFET transistors have revolutionized computing and switching power designs. It is nice to see a new type become available after decades of refinement of MOSFET. GaN transistors offered by GaN systems show a path to cooler running, more efficient and better performing amplifiers and power supplies. The eval unit unfortunately doesn’t show the improved performance due to different target for it. So best to look at commercial implementations that shoot for state of the art implementations.

You can see it a mile away, both are only here to discredit what could be disadvantageous to what they are doing to soon to come Class-D offerings they have
It is not clear why you make jabs at trying to discredit a successful well liked individual like Ralph.

From years of reading his posts it’s clear he is above those games.

Another Class D that struggles with lower impedances?
Yeah, I know the specific technical  arguments for higher impedance speakers, but when it comes to the sonic gestalt, I seem to lean towards those loudspeakers that have lower impedances. Wake me up when there are Class  D amps that handle my preferred speakers as well as the better traditional ss amps do. I’m truly hopeful that such Class D amps can be offered at a reasonable cost.
