If you have reached a certain level of "maturity," you probably have boxes in the basement filled with artifacts known as "vinyl records." We played these dinosaurs of the analog age on gadgets called "turntables," and if we played them enough times -- or spilled enough beer on them -- they developed that combination of crackles, pops and distortion that teary-eyed audio tweaks like to call the "warmth of vinyl." Many adults persist in keeping these records long after the only turntable that could play them has crumbled into dust.
