A cette fameuse distorsion de Hirata? là est le sujet.
Dispre 2 preamp is a successor to previous Dispre, simple differential, openloop concept. The previous Dispre had wide bandwidth, high slew-rate, robust output diamond buffer, and no global feedback. The tax for that concept was higher distortion of low order harmonics and quite high DC output voltage, which resulted in use of an output 3.3u foil capacitor.
