When I joined Hi-Fi News in the mid-1970s, one of that magazine's stable mates reviewed cars. An automotive writer appeared in the pub one lunchtime—"I rolled another one," he said, as he joined us at the bar. It turned out that one of his tasks was to take a car he was testing to the skid pad to see how many lateral G's the car could handle. Of course, the chances of a consumer turning that car over were minimal, but the reviewer was investigating the edges of the performance envelope.

As I became familiar with audio measurements, it struck me that the equivalent of the skid pan test was the thermal preconditioning we perform when we get an amplifier on the test bench. Even if an end-user doesn't drive his amplifier into thermal meltdown, the edges of the envelope need to be explored.

KEF's LS50 loudspeaker was introduced in 2012 to celebrate the English manufacturer's 50th anniversary. Usually, anniversary models are large, floorstanding "statement" designs with a price to match, but the LS50 was a minimonitor, priced at $1500/pair. I reviewed the Anniversary Edition LS50 in December 2012 (footnote 1), writing that it was rare to find a loudspeaker that offers this combination of clarity and neutrality and concluding that within its limits of dynamic range and bass extension, the KEF LS50 "will provide Class A sound for those with small rooms."

Three products are the subjects of lengthy followup reviews in the December issue of Stereophile: MBL's Noble Line N31 CD player-D/A processor, the GoldenEar BRX loudspeaker, and Alta Audio's Alyssa loudspeaker.

Let me tell you how I spent the month of May 1987: I had been musing about a comment made by J. Gordon Holt following the 1986 Summer CES that it seemed that the loudspeaker High End was populated exclusively by planar models: Apogees, Acoustats, MartinLogans, Magneplanars of various kinds, the Quad ESL-63, and an assorted Infinity or two. The problem is, however, that folks as a rule buy speakers made from boxes; boxes priced a little lower than the esoteric beasts so beloved of reviewers. "OK," said Larry Archibald, "how about reviewing some moving-coil loudspeakers? Tell you what. Let's make it interesting; make them box loudspeakers costing under $1000/pair. It'll give you a feel for the kind of affordable speaker that sells in quantity."
