 Generally the differences have to do with noise, distortion and bandwidth.

Most of this has come from the driver stage, but there have been power supply and output section improvements as well.

All the Mk3.x series have the same output section so far- it was the output section that jumped us from Mk.2.x to Mk3. The Mk3.x series have different power transformers too. The Mk3 also got an improved hookup wire.

3.1 and later have improved grounding technique (lower noise). 3.2 has reduced IM distortion as we found a modulation problem that existed in the bias circuit.
