Looks like your pessimism was justified, Pavel. Ah well, no technical progress or useful data, just a promotional exercise and the usual sneering. Comme s'habitude.
Sneering goes both ways, guys. I just thought it might be interesting to compare notes among designers and users.
MEASUREMENTS: Belkin PureAV PF60 Power Conditioner.
I have one of these fancy power filter boxes.
It lives on a shelf in the garage because to my ear it damages the sound of my system.
To elaborate, it does clean the sound of my systems by removing mains dirt, BUT it also adds something else which is not to my taste.
This else is that ferrite sound which somehow gets through.
Dan.

Elvee, while I think your plug is a little confrontational to claim joke, I have to ask if your device provides PFC? It interest me quiet a bit. How much noise will it generate? I'm sure some passive parts would improve it. I would like to hear one to compare, as I don't have a conditioner like the others here so your claim may be less true to it, but who knows, maybe it's heaven.
PFC is massively overlooked. The PF has probably become worse than the noise itself in many ways. It has dulled all live instruments immensely for bands. There are some PFC networks being used for line conditioners, but as filters and not actual power correction.
In fact I make "conditioners" that have some filtration, but primarily provide PFC, and the results on electric guitars (including bass) is nothing less than stunning to an attuned musician.

Hi,
@MaxHeadroom. I tend to agree. Some conditioners just kill the life of the music in the progress somehow.
A good power supply starts with a good power transformer to my ears. Trouble is you almost invariable have to have it custom made.
Cheers, 😉

Very, very nicely done experiment, Dan - it indicates that low level noise, or distortion, is very damaging to the perceived sound - essentially because the brain has to work much harder to filter out the extraneous muck, meaning subjectively "poor" presentation and/or onset of listening fatigue at a very early stage.
From comments so far, it appears that unless a "magical" person pops up, like a Jack in the Box, and pursues this idea with a decent appetite for understanding it will wither up, like so many others, on the huge desert of collective apathy ...

'Ferrite Sound' is something IIRC CH came up with.
Like so many other things from that individual, it's absolute ********. Period.

I await the arrival of Inspector Clouseau to clap me in irons and lock me in the Bastille.
Hi,
Sure can.... And they all know very well that no one will take that step.
Internet law is slow, very slow but we're getting there.
Cheers, 🙂
P.S. Don't hesitate to contact me.

Virtually all systems have "sounds" - but this is not mentioned in polite, objectivist company 🙂 - just a convenient term to refer to the remaining, audible distortion that the setup contributes to the listening experience.
Easy to apply some labels, like "tube sound" and "horn sound" - these are readily accepted by most, and allow them to mentally "picture" the result. But stuff like "ferrite sound" has the sniff of snake oil about it, and is far less acceptable to many, even though it may convey the sense of a certain aspect in the perceived quality to some ... 🙂

Hi,
Mentioned it at least 10 years ago already, Frank.
Prove it is all I heard ever since.
Cheers et bon courage, 😉

Apparently not any actual data, despite the load of new test equipment that you have. 😀
Thanks, Frank ... my suspicion is that many have "learnt" how to not hear differences ... they've been burnt at some stage in the past by getting over-enthusiastic chasing the "new, but not better" variations - and now have gone very grumpy about the whole concept of improving things. It's like a woman has to be 10 times better at doing a job, before she gets respect from the blokes ... 😉
How did you use them? I've found they make excellent, cheap transformers (both for signals and for tweeters, power too) which can be wound by a DIYer for specific applications. Can't live without them now.
