If you have separate secondary windings for the bipolar supply and use dual rectifier bridges does changing the relative phase of one secondary winding relative to the other have any effect on common mode noise reduction?

So you mean that no hi frequency noise can get past a bridge rectifier?
That doesn't seem right.
