Onkyo Marks 80 Years With the $1,699 Muse Y-50 Anniversary Edition Streaming Amplifier
Takeshi Godai founded the Osaka Denki Onkyo Company in 1946 to build phono pickups and loudspeaker cones in postwar Japan, choosing a name that translates to “sound harmony.” Eight decades and several corporate chapters later, Onkyo is marking its 80th anniversary with a limited-production integrated amplifier that dresses modern closed-loop Class D electronics in the woodwork and gold anodizing of its 1990s flagship separates.
Priced at $1,699 and capped at 1,000 units worldwide, the Muse Series Y-50 80th Anniversary Special Edition sits $200 above the standard black-or-silver Muse Y-50 ($1,499), while sharing the same compact 13.8-inch-wide chassis and 250-watt-per-channel (4-ohm) power plant.
Integra M-588 Styling and San Kuzushi Details
For the anniversary edition’s exterior, Onkyo reached back to its early-1990s Integra M-588 dual-mono power amplifier. The front panel and knurled volume dial are machined from aluminum anodized in Champagne Gold, flanked by real American walnut side panels finished in a deep Bordeaux stain. Above the internal heatsinks, the top ventilation plate is stamped in a traditional Japanese San Kuzushi geometric weave rather than standard rectangular slots.
Dominated by a 5.46-inch color LCD, the faceplate displays simulated analog VU meters, source icons, or album art and playback metadata. Even in a three-quarter-width footprint measuring 3.9 inches tall and weighing 10.8 pounds (4.9 kg), Onkyo kept physical bass, treble, and balance controls right on the front apron alongside a 6.3 mm headphone jack.
Axign Closed-Loop Class D and Onkyo Room EQ
Inside the fanless chassis, the Y-50 uses an Axign full-digital Class D controller chip paired with high-current power MOSFETs. Unlike conventional open-loop switching amplifiers whose high-frequency frequency response shifts depending on speaker impedance, the Axign architecture takes its digital feedback loop directly after the output filter at the speaker binding posts. According to the official U.S. Muse Y-50 specification sheet, the amplifier delivers 125 watts per channel into 8 ohms (20 Hz–20 kHz, 0.08% THD, two channels driven) and doubles to 250 watts per channel into 4 ohms (1 kHz, 0.7% THD), supporting speaker loads from 4 to 16 ohms.
As detailed in the Onkyo Muse Y-40/Y-50 user manual, the amplifier includes built-in Onkyo Room EQ acoustic calibration using a supplied setup microphone to measure room modes and speaker distance, managed through the Onkyo Controller mobile app. Network playback runs over Wi-Fi or Ethernet with native support for Spotify Connect, TIDAL Connect, Qobuz Connect, Apple AirPlay 2, and Google Cast, plus Bluetooth (SBC/AAC).
Rear-panel connectivity is unusually thorough for a compact two-channel integrated. Alongside three stereo RCA line inputs, Coaxial, Optical, and USB-A storage ports, Onkyo included a built-in phono stage with a rear switch for both Moving Magnet (MM) and Moving Coil (MC) cartridges. Video sources get an HDMI 2.1 input supporting 8K/60Hz and 4K/120Hz pass-through (with VRR, ALLM, QFT, HDR10+, and Dolby Vision) paired with an HDMI ARC output—allowing a gaming console or Apple TV to route directly through the amp if your television’s HDMI ports are full. Stereo RCA pre-outs and a dedicated subwoofer output round out the analog section.
