"I hope you're decompressing from AXPONA," I recently wrote to a frazzled-looking friend I'd met at this greatest of North American hi-fi shows. Google's spellcheck offered to change decompressing to decomposing. I declined, though it's true that such expos can be grueling—just not grueling enough to stay away.

In these observations about high-end audio shows, fondness is foremost, but a few dark side notes will slip in.

In my high-school days, I visited a friend whose well-to-do dad proudly demonstrated his new Quad ESL system for us. First up was a recording of a man with heavy footsteps traversing the space from left to right. Next came a speeding police car, siren engaged, complete with Doppler tail. I found it impressive, and a little lame at the same time. My friend and I, in love with our own artsiness, preferred Fear of Music by Talking Heads and Drums and Wires by XTC, or (in a pinch) U2's Boy.

It wouldn't have occurred to me that I'd ultimately derive frequent joy from listening to sound effects (though in my case they're usually integral to the music, not apart from it). When I hear Yosi Horikawa's bouncing marbles on Wandering, I prick up my ears and smile. A panting dog on Holly Cole's Temptation, an overhead hovercar on the Blade Runner 2049 soundtrack ... bring it on. A babbling river on Andrew Bird's Echolocations; seed pods on Tom Waits's Blood Money; liquid splashes and crinkling paper on Felix Laband's Dark Days Exit ... yes, please. I don't care if it's a little gimmicky. It's also sensual in the original meaning of the word, an aural pleasure.

The Raidho TD3.8 speakers that, after three months, just departed my home, do the trick of conjuring points in space with great acuity.
