Well, there is a school of thought that some filters/power conditioners etc. can in some circumstances sort of limit the dynamic range of some amplifiers. As if the delivery of current is being slowed when the amplifier demands it for loud/fast transients. Or something. Wonder what effect they have in the impedance?
I've had little experience of any commercial designs so can't comment with any authority myself. It's interesting though, do carry on please!
Cheers...

I'll have a word with Anthony and I'm sure he'll be able to explain better what's happening in a technical sense.

there is mileage in what you say me ole flower, basically a lot of the filters on the market filter out noise very crudely using capacitors in various configurations across the live, neutral and earth, but as you say most have a negative affect on audio equipment being used on our mains supply, now one of the main differences in our mains supply to the USA is unlike our supply where we have a live, neutral, and earth, in the USA they have two lives, and the earth is either connected to true earth ground, or generally the metal chassis of equipment is connected via capacitor to either one of the lives!
i suppose they work on the assumption that because their voltage supplies are only around 110 to 120 volts at full potential, if you were exposed to the naked supply and real earth [ground] you would only be in contact with around 55 to 60 volts,[either one of the lives] which in most cases is not lethal, unlike our 240v...
this may be why filters which are used on our supply that are known to as marco says "sit on the sound" have a different affect on the mains in the USA.
just my rambling opinion on this mind you.

Thanks for that, Anthony. So no folds in the time-space continuum in your listening room, then?

LOL. Call me thick (if fact, I'll do it - 'thicky'; there!) but what's that got to do with Dr Who?
