Pro-Ject MaiA S3 Integrated Amplifiers

The All-in-One Integrated Amp Solution

The Pro-Ject MaiA S3 compact integrated amplifier is the all-in-one solution for your hi-fi system. It's perfect for bedroom, den, office, or apartment or for dedicated applications. You'll love the sound and performance so much, it can be ideal for your primary audio system, too.

Not only does the S3 circuit design constitute a nice upgrade from earlier MaiA iterations, but the enclosure has been enlarged also. While it's still compact in size, the larger footprint allows for an improved circuitry layout in terms of electromagnetic interference. Additionally, the rigid aluminum S3 chassis protects circuitry from RF/EMI.

Sources Galore for All Your Gear

MaiA S3 has enough connections for a system's worth of gear. With eight total inputs, it's ready for any combination of sources. MaiA S3 offers a phono RCA input for MM moving magnet or high-output MC moving coil cartridges as well as three RCA line-level inputs for sources such as CD players. You can also connect digital sources including your TV and/or a CD transport to the digital coax or optical S/PDIF inputs to recruit MaiA S3’s Cirrus Logic CS4344 DAC with a quality up to 24bit/192kHz.

If you want to wirelessly stream music from your mobile phone, tablet, or PC, you can simply connect to the high definition AptX HD-capable Bluetooth 5.0 input and achieve quality up to 24bit/48kHz (better than standard CD quality).

Listen Exactly the Way You Like

For your listening pleasure, MaiA S3 provides versatile output options. It’s headphone-ready for private listening. Or connect your speakers via the 4mm banana plugs, and the low-noise amplifier will provide musical sound with lifelike characteristics. The variable RCA output also allows you to use a subwoofer or a second power amplifier in your system, which is a terrific feature at this price.

This integrated amplifier accommodates all your sources and delivers music in outstanding quality, thanks to its dual mono design and carefully selected internal components. With the supplied remote control you can adjust the volume with the motor-driven analog potentiometer – another premium features! – as well as toggle among the inputs.

Pro-Ject's MaiA S3 is designed and assembled in Europe and is available in black or silver finish. A wireless remote control is included as standard.
