The truth about PFC for audio circuits

[b_force]

I have done quiet a lot of research about power factor correction in audio circuits but I'm stuck in the following.

Officially according to EN61000, everything above 75W needs correction (for consumer products that is)
So, why the question you may wonder?

Well I can't get my head around the fact that there are thousands of amplifiers, tube amplifiers and guitar amplifiers from big mayor brands that don't meet these standards at all.
How do they get away with it?
Are there exceptions for audio? (can't find anything about it, except rumors)
Do they rely on the factor that this kind of equipment isn't being used 24/7 or something?

I think the requirement for PFC only relates to switching supplies or where the incoming mains is fed straight into a rectifier with smoothing caps, this results in a large current drawn at the peak of the mains cycle. With a small number of appliances this is not a major problem but if it was a large office building say with several hundred PC's without PFC it would become a major problem for the electricity suppliers.
