For most people the terms hi-fi and stereo are synonymous, and yet it is clear that there is still a great deal of confusion over what the word "stereo" actually means. There isn't even a consensus of opinion amongst producers of records, designers of hi-fi equipment, audio critics and music lovers as to the purpose of stereo, and considering that the arguments show no sign of diminishing in intensity, it is instructive to realise that 1981 sees both the 100th anniversary of Clement Ader's first stereo experiments and the 50th anniversary of Alan Blumlein's classic patent on stereo.

The problem confronting the magazine reviewer when organising the necessary listening tests to accompany/reinforce the measured behavior of a device under test is complex. There has never been a problem with the measurement aspect; as long as someone has access to the same test gear—and full knowledge of the test conditions—then he should be able to replicate the critic's findings exactly (assuming an infinitely narrow spread of behaviour from sample to sample—a rasher assumption with some manufacturers' equipment than of others). However, when it comes to determining reliably the audible (or inaudible?) effects on music program by an amplifier/cartridge/loudspeaker etc. then the going gets tough.

Editor's Note: The forthcoming August 2017 issue of Stereophile is No.451, but 55 years ago this summer, J. Gordon Holt was putting together the first issue of what initially was to be called The Stereophile. Here is Gordon's editorial leader from that issue, published in November 1962.

How do you rate as an audio expert? Test yourself on these 25 questions.

All of the following are multiple-choice questions, dealing with things that every audio hobbyist should know, either before or after completing the test. Most of them are easy, but take your time in answering and don't jump to conclusions. Some of the questions are quite tricky, and wrong answers will be subtracted from your final score, so read them and the possible answers carefully before committing yourself. Don't guess if you aren't fairly sure.

Editor's Note: In the 21st Century, lossy audio data compression, in the form of MP3 and AAC files, Dolby Digital and DTS-encoded soundtracks, and YouTube and Spotify streaming, is ubiquitous. But audiophiles were first exposed to the subject a quarter-century ago, when Philips launched its ill-fated DCC cassette format. What follows is Stereophile's complete coverage on both DCC and its PASC lossy-compression encoding from our April 1991 issue.—John Atkinson

Editor's Note from 1974: As you can read in the following "As We See It," the last issue of Vol.1 No.12 (cover dated "Spring 1966") was perhaps not as "strong" as it might have been. If we had been doing things according to Proper Business Practice, we should have held back our best articles and our gutsiest reports until that issue, as a high-powered incentive for our subscribers to renew their subs. We didn't. There were better articles and a greater variety of topics covered in earlier issues, but Issue 12 was significant in that it set the pattern of topic emphasis, and the balance of reports versus other editorial material, that was to continue more or less unchanged for the next 7 years.
