DENON, September 1994 PMA-αS1 - amplifiers | ShowaAudio · デンオンカタログ平成6年9月

A 6-page brochure with two centre spreads on the DENON PMA-αS1 - the flagship integrated amplifier of the αSensitive series, paired with the DCD-αS1 of the same 1994. The cover is a close-up of the gold front panel with a huge VOLUME knob, BALANCED INPUT and INPUT SELECTOR keys (PHONO/TUNER/CD/AUX/TAPE), and three headline phrases beneath the unit: UHC Single Push-Pull Circuit, Single-body Sand-cast Chassis with Radiator, New Inverted Σ Balance Circuit. The second spread repeats the αSensitive language - black background, a moon over a desert canyon with arch-like windows in the rock (Utah, unmistakably), a vertical line “創世紀が聴こえてくる” (“you can hear the dawn of an era”), and the αSensitive logo with the same small red 愛 used on the CD flagship. Inside, the circuit story: UHC Single Push-Pull output stage on the large-current UHC-MOS elements, MOS-FET single push-pull, OTL without an output transformer, and the new inverted Σ balance circuit (shown with a block diagram of inverting and non-inverting amplifiers). The chassis is a single-body sand-cast frame with two massive heatsinks structurally integrated on either side, plus a sand-cast weight base on the bottom - the same philosophy as the DCD-αS1. Connectivity is generous: BALANCED XLR, PHONO with auto MM/MC switching, CD, TUNER, two AUX, two TAPE loops with REC OUT, two SPEAKER pairs, plus PRE OUT / POWER IN for bi-amping or for use as a standalone pre/power. The numbers: 50 + 50 W into 8 Ω (doubling to 100 + 100 W into 4 Ω), THD 0.007% at the main stage, 0.002% at the pre stage, SNR 108 dB on LINE / 91 dB on PHONO MM, output impedance below 0.1 Ω, weight 25.5 kg, price ¥400,000 before tax. Paired with the DCD-αS1 at ¥500k it added up to a clean ¥900,000 stack before tax - exactly the system αSensitive was conceived for: “a flagship built with passion by DENON’s sound engineers” for those “who love music with all their heart”.

創世紀が聴こえてくる。	You can hear "Genesis"
歡び。哀しみ。笑い。熱情。恋心。鎮魂。無頼。啓示――。人が感じ得るもの、そのすべてを歌うために音楽は生まれ出ました。演奏者の魂から放たれた旋律に身をさらす恍惚と畏れは、まさに音楽でしか表現し得ない不可思議です。私たちはこの感動という輝きの原点にいま一度戻り、それをプリメインアンプの世界で実現すべく開発をはじめました。めざすのは、手になじんだ道具のように身近で、しかも"かつてない純粋な再生"を奏でてくれる1台…。PMA-S1。それは、新たなるアプローチ、そして感動の真理。世界のオーディオファイルの磨かれた感性に捧ぐ"Sensitive One"シリーズが達成した、DENONプリメインアンプ新世紀モデルです。長年培われたアンプ技術が可能にしたブレイクスルーが描くのは、音楽全体がひとまわり広がりをみせたような溢れる生命感。そして、圧倒的な無垢なる静けさ、微かな漂いのなかにも体温を感じる緻密…。いま、あなたの聴きなれたソフトから、見知らぬ風景が響き出ようとしています。ついに、音楽感動の「創世紀」へ。「原点の原点」へ。	Joy. Sorrow. Laughter. Passion. Love. Requiem. Rebellion. Revelation. Music was born to sing of everything that a person can feel. The ecstasy and awe of surrendering oneself to a melody released from the soul of the performer is a wonder that only music can express. We returned once more to the origin of the brilliance called emotion, and began development to realize it in the world of integrated amplifiers. The aim is a single unit that feels as close as a well-worn tool, and yet plays "unprecedentedly pure reproduction"... PMA-S1. It is a new approach, and the truth of emotion. It is the new-century model of DENON integrated amplifiers, achieved by the "Sensitive One" series, dedicated to the refined sensibilities of audiophiles around the world. The breakthrough made possible by long-cultivated amplifier technology paints an overflowing sense of life, as if the whole of the music had grown one size larger. And an overwhelming, spotless silence, a precision in which even faint drifting conveys the warmth of a body... Now, from the software you are used to hearing, an unfamiliar landscape is about to resound. At last, to the "Genesis" of musical emotion. To the "origin of origins".
"S1シリーズ"は、音楽を心から愛する全国のオーディオファン、ハイエンドユーザーの磨かれた感性に応えるために開発されたDENON高級オーディオシリーズです。	The "S1 series" is DENON's high-end audio series, developed to respond to the refined sensibilities of audio fans across the country who love music from the heart, and of high-end users.
