Our Delta L-1011 emerged from the cloud split-seconds before its wheels touched the waterlogged ground. "How much lower does the cloud cover have to be before they divert us to another city?" I asked Tom Norton. "About an inch," came the phlegmatic reply. (Ex-F4 pilot TJN categorizes any landing you can walk away from as "good.") But at least we had reached Atlanta, after a saga of air-traffic control problems, weather delays, and missed connections. (Does anyone remember taking a flight that <I>wasn't</I> full, <I>wasn't</I> late, and <I>wasn't</I> sweaty and stressful? Wasn't deregulation supposed to improve service by increasing the choices available to travelers?)

MACH 1 Acoustics? Cute name. Mach 1 is, of course, the speed of sound&mdash;the speed at which a loudspeaker's acoustic output is forever constrained to travel. Quite a fitting choice for Marc McCalmont, Marine and jet pilot turned speaker designer. Marc retired to Wilton, NH together with Melissa. (Oops, that should be <A HREF="http://www.mlssa.com">MLSSA</A&gt;, the well-known acoustic analysis system&mdash;not Marc's girlfriend.)

<B>Jonathan Scull: </B>Gordon, please tell us what you see as the basic difference between single-ended and push-pull.

We have to talk. Are you sitting comfortably? Is the reading light okay? Have a little something to drink at hand? (Audio is thirsty business.) The audio world is abuzz over the reintroduction of the single-ended triode amplifier. This is the first of three reviews of such amplifiers I'll be bringing you, along with two speaker systems with which to play them.
