In poker, "tells" are subtle physical or verbal actions that give away the strength of players' hands.

I am not a poker player, but I am an audiophile, and I use a variety of "tells" as my prime tools in critical listening. You know my worn-out line: "You can't hear what you're not listening for."

Why am I once again falling down the rabbit hole of alternating current? A while back, I committed to listening to SMc Audio's AC Nexus power conditioner, designed by SMc founder Steve McCormack and distributed by dealer Hi Fi One.

Technics, an arm of the Japanese giant Panasonic Corporation, has long been a major player in the hi-fi world, even if, in some recent decades, it stayed below the radar.

In the 1970s, analog-centric audiophiles particularly praised the Technics SP-10, the world's first direct drive turntable. Created by Matsushita engineer Shuichi Obata in 1969, the SP-10 and its successors became the standard in vinyl playback for American radio stations during that heyday of broadcast radio.
