The WXA-70A is a Streaming Integrated Amplifier by Yamaha that delivers 55 watts x 2 channels into 8 ohms and 105 watts x 2 into 4 ohms (20 Hz-20 kHz, 0.06% THD, 2 channels driven); 165 watts into 4 ohms (1 kHz, 10% THD, 1 channel driven). It was released in 2026. Minimum impedance of 4 ohms makes the WXA-70A compatible with a wide range of loudspeakers. Thanks to its built-in ESS SABRE ES9039Q2M DAC, you can play digital sources directly without the need for an external DAC unit.
Yamaha replaced the older Yamaha WXA-50 with this model. Follow the link to read our detailed comparison of these models:

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 Yamaha WXA-70A is rated at 55 watts RMS into 8-ohms. Yamaha provides this wattage at a THD (Total Harmonic Distortion) of 0.06% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 55 watts into 8-ohms (20-20k) at 0.06%
- 105 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)

Which speakers suit the Yamaha WXA-70A?
55 W into 8 ohms, 105 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
When pairing the Yamaha WXA-70A 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.
