I've noticed that a lot of early transistor designs are differential circuits.
I suppose that, in a way, given the nature of the transistor, there is good reason to try and cancel distortion with such a circuit.
Most of the classic preamps are asymmetrical class-a gain blocks, though.
Any reason why they didn't catch on? How would you compare the sound to the more typical 3-transistor circuits?
