Well, the mailer from King Snake Russ Andrews arrived today, featuring a 'product focus on fuses'. He sells fast and slow blow ones - cryogenically treated, and no longer subject to just some basic burn-in process, no - they get Process-Q...
Still, they're bargains in comparison with the ones in this thread, at only £25 each.
There's also an interesting (in what way I'll leave you to decide) intro, which warns of the rubbishness of double blind testing - it's unnatural, blunts the ability to discriminate and causes 'considerable psychological stress'. Even if you accept that (which I don't), surely your own, in-house people would become accustomed to it, and they should be able to do double blinds in order to satisfy themselves (and RA) that their products do what they say on the tin? The argument is considered to be supported by some guy from Stereophile, who couldn't tell the difference between amps from Quad, Naim and a TVA valve amp under DB conditions. My conclusion about that would be rather different.
Reading the letters and readers' reviews, I think RA is basically a sort of cult leader to a certain type of person.
