I have cooked this circuit up during the last couple of days, it is single ended and borrows the output stage from the famous John Linsley Hood Class A amplifier. Distortion figures and PSRR look quite nice, but the circuit has only been simulated, I have a TDA1545 DAC to finish If I could only keep my mind on a single project. If my calculations are correct, the amp will deliver 250mW into a 32Ohms load in class A.
