So, Norton put a link to an article in the shout box. http://www.esquire.co.uk/culture/news/a8618/are-the-audiophiles-hearing-something-were-not/ (http://www.esquire.co.uk/culture/news/a8618/are-the-audiophiles-hearing-something-were-not/) In the article, the author said that one of the audiophiles went on about "something he called dirty power", as if to suggest it doesn't actually exist. So, I wanted to give a real world, non-audiophile example. Some of you may know that I work as a portable x-ray tech. One of the ancillary services that we offer is EKGs. So, I've done 2-5 EKGs a week for about 20 years now. In that time, I have encountered several instances where I was unable to get a good trace due to electrical interference (i.e.: dirty power). Usually moving to another room will take care of the issue. When it doesn't, I have to give the test over to one of the techs who has a battery powered machine. We have one account (a very rural facility up in Clarion county) which does a lot of EKGs (they deal with a lot of psych meds, which require regular cardiac monitoring) and always has dirty power. So much so that my supervisors decided the best solution was to leave a dedicated battery machine on site so that they get a reliable trace regardless of which tech goes there.
Do I think that the idea of dirty power is exploited by high end companies and is often a solution in search of a problem? Sure, I'm virtually certain. Do I think it is something made up by the audiophile world, as the article seems to suggest? Absolutely not.

Oh, and if the author thinks that audiophiles are fastidious, he should spend some time with cardiologists!

The company Furman, who makes some audiophile quality power conditioners, has made their name (and probably primary income) in power conditioners in the medical field. If I were to bother with a line conditioner, that is who I'd go with.

One of my two is a Furman.

Oh ya it's definitely real, also definitely exaggerated/exploited to sell units. We have had days in the rec studio where the the signal is clearly different, sometimes audibly "dirty", other times the signal wasn't as full/strong. I'm talking a one day difference where we shut the amps down, didn't move a single knob/connection, locked the door, and came back the next day to a different guitar tone, vocal signal, ext ext. In a studio situation where you have the ability to play tracks from day 1 and day 2 back to back it is easy to hear a difference. Granted a lot of factors in play here, but the engineer will literally call and say no-go today due to dirty power.
Also in my own home (located next to a large transformer) I have integrated a tripp-lite medical grade power conditioner/noise suppressor and it cut down on hum in amps with a lot of pre-amp gain.
My house was also built in 1910, i'm sure more modern electrical systems are better and solve some of these issues with better shielding and such.

Cool story!
