Staccato OSH-DHb OpAmp

The Open Sound Hybrid Discrete OpAmp improving the sound of high-end DACs and preamplifier.

The use of J-FET, in both input and output stage, in combination with high bias current, had result in low Open loop distortion with dominating of 2. harmonic. The source follower at the output using an active current source which allow higher output current than the bias current.
