Integrated amplifiers — Pro-Ject MaiA S3

The MaiA S3 is an integrated amplifier with built-in DAC and Bluetooth from Pro-Ject, sitting below the MaiA DS3 with more modest output power in a smaller chassis. The MaiA S3 brings Pro-Ject's considered engineering to a compact wireless-capable integrated format.

Key specs that matter

One balanced XLR input and three single-ended inputs are provided. Output power is a modest 23W into 8 ohms, rising to 40W into 4 ohms. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is a comparatively modest 69dB, with total harmonic distortion plus noise under 0.04%. At a remarkably compact 206 x 55 x 153mm and 1.07kg, the MaiA S3 maintains a space-efficient integrated amplifier chassis with built-in wireless streaming.

Sound and use context

Expect an accessible, dependable amplification character suited to modest-power desktop or nearfield applications, with the built-in Bluetooth connectivity offering genuine wireless streaming convenience.

Pairing

The built-in Bluetooth connectivity covers wireless digital sources directly, and the modest 40W-into-4-ohms output suits notably efficient compact loudspeakers.

Alternatives

Pro-Ject's own MaiA DS3 offers a considerably more powerful alternative with a built-in phono stage within the same broader catalogue.
