I agree the clear explanation is very helpful - thank you Wireman
You mention you're measuring noise - is there an easy way for a non-qualified person to measure noise on their home power supply or does this involve specialist equipment?
Audioprism and, interestingly, PureAV, both make 'home' devices anyone can use for detecting noise on their own mains supply - they're called "Noise Sniffers". You simply plug the device into a mains socket and it converts any electrical noise it finds into audible noise you can hear (PureAV's version also displays the noise level). Plug the device into your mains conditioner and hopefully the mains noise will disappear - remove the mains conditioner, and the mains noise will likely reappear.
The PureAV version can be bought for about £50 (but I think this, like all PureAV's mains conditioners, is in the process of being discontinued). The Audioprism can be bought, or it can be hired from Russ Andrews. Personally, I think the PureAV "Noise Sniffer" is the most versatile of the two since as well as being able to adjust sensitivity levels, the display is useful too, and it has a memory function so you can compare readings.
In my view, it's worth testing your mains first with a Noise Sniffer before buying a mains conditioner - if your mains is clean you won't need a conditioner, and if your mains is 'dirty' it'll prove how effective your conditioner is (or isn't) at dealing with the problem - or if it's dealing with the right problem. Everybody seems to assume their power is 'dirty' and they need a mains conditioner - and that isn't always the case. Some hi-fi Mains Conditioners when used on a mains supply that is actually quite clean really do have a detrimental effect (it's measurable), but I wouldn't put the PF30 in that category - the PF30 doesn't work that way.
If a Tacima has a good effect in your environment, the PF30 should be at least as good and most likely better (possibly a great deal better). If a Tacima doesn't do anything for you, I'd avoid this PF30 (and PF40, 50 and 60), since the circuitry inside is largely based on the same principles.
