Pro-Ject MaiA DS3 Integrated Amplifier


Pro-Ject MaiA DS3 Integrated Amplifier


The Pro-Ject MaiA DS3 (My audio integrated Amplifier) is our new reworked all-in-one compact amplifier solution. It combines both, analogue and digital inputs to suit all different sources. With its 140 watts per channel at 4 ohms you can easily power your favourite speakers. The whole electronics are packed into a beautiful machined full aluminium case which protects it against outer interferences.


Pro-Ject MaiA DS3 Integrated Amplifier

An integrated amplifier doesn’t have to be physically large to be high performance and fully featured. When I read the initial press release for the Pro-Ject MaiA DS3 I thought, “There’s an amplifier that seems to fulfill all the requirements needed to be a really great integrated choice for a lot of audiophiles out there” and luckily I was able to get a review sample in short order.

The Pro-ject MaiA DS3 has both analog and digital inputs as well as a built-in headphone amplifier and phono preamplifier that supports both moving magnet and moving coil phono cartridges. In short, the MaiA DS3 can, in one modestly sized box, serve as a compact centerpiece of a high-performance audio system that can fit into the smallest space or desktop system and still deliver full-range high-fidelity sound. It even has a remote control.
