Quartz controlled, the Armageddon is an OVERdimensioned toroidal trannie
with a dropping resistor.

Assuming it goes round at the right speed, the only other thing might be
external magnetic fields generated, in the main, by the transformer. Hence
the toroidal which has a low field. But if you haven't got any audible
induction from the PS, you should be ok.

Why is it so difficult/expensive to achieve a steady sustained motor speed?
There's quite a body of measured evidence that suggests variations between
PSUs, and this points to 2 things - average and sustained speed.

If it's not difficult why do people spend so much money on things like
Lingos, Origin Live PSUs etc?

I do (of course!) accept that placebo effects arise in all matters hifi, but
things like pitch and stability are quite easy to listen for - so there must
be some truth in these exotic PSUs?! I've never noticed noise from a power
supply but I can hear differences in stability (say a decaying piano note) -
even on quite expensive turntables.
