One of the things that distinguishes a dedicated audiophile from Joe Q. Public is that he has some notion of what audio fidelity is all about.

A number of recent letters have accused us of snobbishness and elitism because we devote so much space to reports about components that "common folk" can't afford. We are "snobbish" because we seem to look down on anything less perfect than a Wilson WAMM speaker system or an Audio Research SP-10 preamplifier.

Far from being chastened by these letters, I am proud, to declare that they are right on target.

This issue contains a report on a truly ingenious little device called the ABX Comparator, which takes the fraud out of subjective testing. It does this by making its own selection of source A or source B for each listening trial, without telling you which was selected. Only after all the tests will it reveal what you were listening to each time. "Score" sheets are provided so you can list your guesses, compare them with the cold, uncompromising truth, and file the results for posterity. Or better still, for the first hard evidence that has ever been presented that a lot of people can hear differences that cannot as yet be measured.
