...damn I love the people who fall for that b*ll*cks!
Almost as much as those who spend a small fortune on a 'fancy' mains lead then plug it into a socket in the wall...
I made my cables for myself; did think about marketing them but there's just so much rubbish out there touted as
the perfect cable that I just couldn't be *rsed! Even though mine
are about as good as you can get
The sound engineers I work with assured me that once I'd got past the age of 19 all the technobabble is just so much scotch mist; it's a very
subjective subject; and that's the main reason that even the biggest manufacturers shy away from 'blind' comparison tests...
...very unscientific I know but I tweaked
my designs using the thunder at the beginning of Dire Straits 'Brothers in Arms' as a benchmark; for years I never even knew it was there!
I also have to 'beg to differ' on your 'a wire is a wire' assertion; I've made three versions of my cables...
...one using plain copper wire, one using silver-plated copper wire, and another using pure silver wire; and they all sound different.
I also use only copper and silver in the construction; none of this 'lump of solid brass with a thin plating of silver or even (Gosh!) gold' tacked onto the end of some 'cryogenically treated' OFC copper...
