Some people think that the DC current through the OPT actually is a desirable feature of a SET, despite the air gap and lower primary inductance. The DC magnetization moves the operating point of the transformer up the BH curve away from the flat spot around zero current into a more linear region where there may also be less hysteresis to confound the sound. The slope is no longer symmetrical, so any distortion will have a heavy 2nd harmonic component which is consistent with the overall SET theme. I'm no magnetics expert, so I hope others will elaborate.
