You are looking at ripple reduction from a measurement standpoint and then correlating it with the noise people hear through high efficiency speakers. Could some of that noise we hear be coming from someplace else, like low frequency noise from the power line and DC offset that makes transformers hum? I'm not sure if powerline conditioners take care of this and i am not sure you can detect this additional noise at the output without being able to experimentally isolate with some kind of external filter. So maybe this is just a non-sequitor.
Observe, before you think. Think before you open your yap. Act on the basis of experience.

... hum (and buzz) have very many possible causes, even if this particular discussion focuses on just one of them. Sorting them out is always going to be a challenge :^)
Look at the small H chokes and amount of uF's in the filtering.
That is most likely the issue causing some mVAC at the OPT secondaries.
If you sit far enough back from the speakers, it is probably not a big deal once the music is playing loud enough.
If you need a really quiet SE 45 amp, try active parafeed finals with C4S plate loads.
