If you love Sonos but want to keep and integrate your own high quality speakers, then the Sonos Amp is for you.

With a mighty 125 watts per channel, it’s ideal for all speakers, including floorstanders and installation speakers.

A wide range of inputs also make the Amp ideal for connecting a TV, games console, turntable (with phono pre-amp) or other music device.



With a mighty 125 watts per channel, the Amp is over twice as powerful as the Sonos Connect Amp.

This level of power makes all the difference with inefficient speakers or for when you’re running larger speakers that need to fill a big room with immersive sound.

For even more bass, use the sub output to connect your choice of powered subwoofer.


The Sonos Amp isn’t just about power, it’s about sound quality, too.

Featuring a Direct-digital feedback amplifier with discrete output stage, the Amp uses separate components for the highest quality sound and lowest distortion.

Obsessive attention to detail even runs to black, painted circuit boards.

These radiate heat better, keeping the Amp cooler for longer.
