I believe pro studios do consider clean power very important. I read through a thread on these forums in which a pro cable designer gave very detailed and complex reasons explaining how dirty power destroys a stereo image. He actually designed and installed cabling for Abbey Road studios (if I remember correctly). The man clearly knows his stuff and is extremely experienced. It was that thread which got me interested in trying one of these mains cables. I think it's worth a try.
There seem to be a lot of fragile egos and paranoid types here. I just wanted an open discussion on the subject to help with my decision.
I'm going to order one of these cables and report back...
Blues, there are a few of us on here who do know what we are talking about, and have designed equipment for use in studios.
As a general rule, clean power is a good thing. In electronics, noise is hard to handle if it is in the same frequency range as the required signal. In the case of mains, the required signal is 50Hz, and the EMI is many many multiples of that. It is very easy and cheap to filter out main noise for a few pennies spent on a VDR and a capacitor, and the place to do it is where the mains supply enters the equipment enclosure. Thats why and where equipment manufacturers do it. You have to remember that the internal power supply components also make excellent filters in their own right.
The UK is blessed with clean and stable mains, but if you live somehwere with really poor mains, distorted waveforms, large spikes, DC offset, then a mains filter or mains regenerator may make some sense.
What won't make any sense is a fancy mains cable with a daft name. Its a piece of wire for goodness sake. What could it possibly do?
If you could link to an explanation of how a magic mains cable improves things (from someone other than a cable seller or manufacturer), I would be very interested. Perhaps a link to the Abbey Road chap you mention above...
Thanks Andy. This is the type of reply I was hoping for...someone with some constructive knowledge. Wireworld do say that their cables filter out all but the 50-60 frequency? The 'Abbey Road chap' posted 4 or 5 times in a cable thread on here but I can't remember which one it was.
I find it hard to believe that every review of mains cables is complete BS, including those on WHF! They are so specific about the character of various cables! Are they all just lying or deluded?
After reading your post I am now having doubts though. Maybe I'll spend the money on a decent USB cable haha
