Quelqu'un parmis les érudits de ce forum a t'il eu l'occasion de se pencherr sur ces amplis en DIY ?

The hifisonix kx2-Amplifier features outstanding distortion and noise performance,
coupled to switchable class A, AAB or AB operation. It delivers 28 W peak (15W RMS) class A into 8 ohms at less than 20 ppm distortion,
and >80 watts RMS into 2 Ohms at 0.2% distortion.
