Yamaha DSP-A3090 Flagship
YAMAHA DSP-A3090 — THE WORLD'S FIRST DOLBY DIGITAL AMPLIFIER. Curated. Not an online yard sale. In 1995, Yamaha put a Dolby Digital decoder inside an amplifier — every surround receiver since follows the path this one started. In November 2025, the Hi-Fi Hall of Fame inducted it for that reason. It sold for $2,500 (about $5,337 in today's dollars). This unit went through the full Black Panel Audio process: inspected, tested, and cleaned inside and out; all pots and switches treated with DeoxIT D5/F5; PRE OUT to MAIN IN jumpers installed and verified — it plays out of the box. 30-DAY WARRANTY INCLUDED. Specs: 7-channel amplifier, 80W/ch into 8 ohms (20Hz-20kHz, 0.015% THD) for front L/C/R; discrete output transistors; Dolby Digital (AC-3) with 6 modes plus Dolby Pro Logic; 11 Cinema DSP + 12 Hi-Fi DSP programs; MM phono stage; pre-outs and main-ins; optical/coax digital inputs; AC-3 RF input for LaserDisc; front swing-down panel with headphone jack and front A/V input; about 47 lbs. NOTE: no remote included with this unit; a couple of cosmetic dings — see photos. Ships double-boxed and insured from Las Vegas; local pickup available. BLACK PANEL AUDIO — Inspected, tested, and cleaned. 30-Day Warranty Included.
