Do any of these power conditioner companies provide measurement data - at the analogue output - with and without them?
It seems some are happy to show noise sniffer type stuff or oscilloscope measurements directly off the conditioner on the mains side - and use this as proof that they're working - but I've never seen anything out of the speaker terminals or DAC output. Something like a Devialet would be perfect for this.
I'm not saying it can equate to what's good or bad SQ, but it should show an obvious difference before and after, using any of the tests experts in this stuff use. I.e. Ok so it reduces noise on the power line, but did that noise make any audible difference at the output in the first place, or did the audio equipments power supply just deal with this anyway. But if so, by how much did the conditioner improve the situation? Surely it would be easy and obvious to get measurements just to prove it's not all placebo?
I started getting interested in the idea, but the more I read - by any competent scientific body - the more I'm inclined to believe it's voodoo. But I'm ready to be converted - just not by listening to one and convincing myself it's working.
I'd like to see someone like archimago put one through its paces to be honest.
