SA-9500 bias adjustment ?

Once the distortion is minimized past a certain idle current level, all that changes is the heat dissipated increases as idle current is increased.

You need a distortion analyzer to accurately spot that point.

The distortion levels argued in the thread (the "blameless amp") are much lower than the 9500 ii delivers, the difference is swamped by the simplicity of the design.
