DENON, April 1994 DCD-αS1 - CD players

A 5-panel gatefold brochure for the DENON DCD-αS1, the absolute top of the αSensitive series and a radically more expensive sibling to the DCD-αS10. The αSensitive manifesto: the small red 愛 (“love”, read as “ai” in Japanese) next to the logo is a bilingual pun that adds an “S + ai” reading to the English word “Sensitive” - something like “sensitive to love”. DENON’s premium line for audiophiles and hi-end users who, in the catalog’s own words, love music from the heart. Instead of conventional slot loading, the unit uses a top-loading mechanism with a special air seal on the lid, shielding the optical block from stray light and internal vibrations. Inside, every DENON technology in its maximum form: ALPHA Processing on a dedicated LSI, Advanced Sign-CO FA S.L.C. (the upgraded Lambda Super Linear Converter), 20-bit 8x oversampling digital filter and GIC 3rd-order analog filter. The mechanics centre on a sand-cast extra-thick chassis with a 6 mm extruded aluminium bottom plate and a heavyweight steel reinforcement, plus a three-stage floating suspension for the pickup block (sand-cast base + oil damper + two-stage spring isolation). The disc stabilizer is machined brass with wood inserts; the pickup drive runs on a T-armature with ruby bearings; the spindle is a cogless motor with a solid 6 mm shaft. For outputs - three digital I/O systems (TOS-Link, BNC, COAXIAL) plus AES/EBU balanced XLR for output, and analog through RCA + balanced XLR. The numbers back it up: SNR 120 dB, THD 0.0015%, weight 20 kg, price ¥500,000 before tax - 2.7× the DCD-αS10 in the same year and the same series. This is the summit of what DENON did in CD playback.
