As to power conditioners, competently designed audio equipment "conditions" the power coming out of the wall outlet by using the transformer, rectifier and filter capacitors in the power supply section. Clean DC is supplied for amplification. No further conditioning is needed and I've never used any.
Johnk,
so in your opinion, a power conditioner is just an overpriced surge protector? [/quote]
That's about the extent of its possible usefulness.
John, the unit doesn't have a legitimate function regulating the incoming power (as I mentioned above)?
