Yes-sounds promising, primarily for the lack of heatsink. Imagine how small the enclosures will be now.

"THD: <0.01%, 20Hz – 20kHz"

Not very exciting... Let's see their curves first in order to see if they are load and frequency independent.

In the 2nd link over on the right side of the page a separate write-up states:
"In the Cell Alpha, GaN Systems’ transistors are designed into the power supply, which can deliver peak transients of nearly 750W. The Cell Alpha power supply fits in any space, creates minimal heat, and supplies the system’s continuous and transient power requirements."

How does putting GaN transistors in the power supply help? I thought their use was as output power transistors?

looking at the other Axign implementations I have high hopes.

It also says “DC – 40kHz +/-3dB”, so no brickwall at 20kHz like you see in the other Axign controlled amps (SMSL VMV A2 and AS400 and the Harman Kardon Citation Amp.). Nice for bats and people using it to keep cats out of their garden ;-)

Audio amplifiers becoming yet closer to being appliances. What's the hobby interest in that? :confused:
