Hi Rave. I largely agree with you about snake oil mains cables. Have you seen the £2k Nordost ones? They come in a lovely wooden box, worth more than the cable. BTW the dealer markup on cables is fantastic. However I also believe that signal integrity is important, including the mains. You can't expect a 50 pence IEC lead from CPC to perform as well as one made up with an MK plug, a decent IEC, with some decent cable. This will mainly be down to quality of construction, rather than materials. I make my own mains cables up, of the quality that sell for between £40 & £80. They cost around £6 to make, and use screened CY mains cable, as used in industry. It is of course reasonable to suggest they don't alter/improve the sound one bit, but for £6 I don't care.
However, the one place where cables do make a difference is interconnects. I have a Chord Chrysalis and the slightly dearer Chord Cobra, and there are distinct differences between them. I won't bore you with the details, but my wife can hear the difference, can she have the £500, or was that for mains cables only?
Also, an earlier thread suggested that a decent hifi was only any use if you listened to classical. Well, I have seven classical CDs, which I never listen to, out of a 600+ collection. This collection includes what could be termed as dance, Orbital, LFO, FSOL etc. Play these on a mediocre system and the bass will be muddy and un controlled, or else rolled off. On a good system, the bass goes way down, but it is tight, punchy and actually playing a tune. I just tire of the stereotype that all 'audiophiles' listen to Classical & Jazz. But then if you've been to hifi show, even the manufacturers seem to think this
