Good argument. It makes sense that the rectifier tube version wouldn't make a difference in performance or sound unless defective or if the PS was being operated near design limits. If b+ voltage variances occur with different rectifier tubes causing an effect on biasing of signal amplifying tubes I could see that causing an a distinct difference in perceived sound of rectifiers among those unaware of biasing.

I get SS vs. tube rectification having an effect on sound though due to switching noise and reverse leakage found only in solid state diodes....Which makes me wonder how bad selenium rectifiers are compared to tubes and silicon diodes....
