I don't know about measurements but I can tell you that my Ayon Tritton 3 is very quiet and has very black background. It's also very dynamic in pentode mode as well.
Ayon measurements
I was wondering if anyone could point me at a set of measurements for an Ayon amplifier, something like those that Stereophile often provides, particularly THD+N and the sine wave frequency spectrum showing harmonics. Although I feel that listening is the ultimate test, I like to use the measurements as a baseline for how well engineered a product actually is. I've looked high and low for measurements for any Ayon amp, and haven't found any yet. Thanks,
