The Muse Y-50 is a streaming integrated amplifier by Onkyo that delivers 125 watts x 2 channels into 8 ohms and 250 watts x 2 channels into 4 ohms. It was released in 2026. It is a 2-channel design using a Class D output stage. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It has a built-in DAC, so you can play digital sources directly with no separate DAC unit needed. It also has a phono input, so a turntable can connect straight to it. The Onkyo Muse Y-50 has an MSRP of $1,500.
There are 4 Onkyo amplifiers in our database. Below you can see the main specs of these amps.
Onkyo Integrated Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Onkyo Muse Y-50 is rated at 125 watts RMS into 8-ohms. Onkyo provides this wattage at a THD (Total Harmonic Distortion) of 0.08% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 125 watts into 8-ohms (20 Hz-20 kHz) at 0.08%
- 250 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 100dB Signal to Noise Ratio

Need more power?
Onkyo Muse Y-50 is rated at 125 watts into 8 ohms, which puts it in our 121 to 180 watts band. The next band up is Over 180 watts, which is worth about 2.3dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the 91 to 120 watts band and better speakers.
When pairing the Onkyo Muse Y-50 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.

Onkyo Muse Y-50 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Power nearly doubles into a harder load, 125 watts into 8 ohms rising to 250 into 4, which points to a power supply with real current in reserve.
- ✓Class D output stage, so it runs cool and wastes little power as heat - which is how it fits in a small case.
- ✓Signal-to-noise ratio of 100dB, so the amplifier itself should be inaudible between tracks.
- ✓Built-in DAC handling 24-bit / 192, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Digital inputs cover 1 optical, 1 coaxial and USB.
- ✓Phono stage built in, so a turntable needs no separate preamplifier.
- ✓Streams over the network without a separate streamer: AirPlay 2 and Chromecast built-in.
- ✓Bluetooth (version 5.1) for playing straight from a phone.
- ✓Pre-outs (Yes) leave room to add a power amplifier or an active subwoofer later.
- ✓Dedicated subwoofer output (Single).
- ✓Headphone output (1/4).
- ✓Detachable mains lead (IEC 2-prong).
- Nothing the published specs count against it.
