The new Pro-Ject Maia S2 all-in-one integrated amplifier takes most elements of its predecessor’s success. However, the “My Audio Integrated Amplifier” S2 takes advantage of some improvements that allow it to gain in performance.


On the outside, we notice a new and beautiful aluminum case. This integrated amplifier is more than the “Swiss knife” of the Hi-Fi, it takes less place than a Michelin guide!

On the front panel, there is a rotary volume button associated with 2 small push buttons that allows the selection of the 9 inputs. Pro-Ject added a headphone output in 6.35mm stereo format.


The back panel offers all the essential digital and analogue input options, and even more: 1 phono input (MM and high level MC), one USB type B, 2 Toslink optical, 1 S/PDIF coaxial, 2 analogues and 1 variable output (Sub or Zone 2) in 3.5mm jack format.

Of course, there are also speaker outputs that must be used with banana plugs only.

Despite its ultra compact size, the Maia S2 allows the connection of 9 sources at the same time.


The internal converter is a Cirrus Logic CS4344 on the Delta Sigma principle. It offers a resolution of 24 bits in 192 kHz, among others on the asynchronous USB input.

The Bluetooth input is aptX compatible, and provides an excellent quality and seamless transmission, thanks to the dedicated antenna on the back of the device.

The manufacturer has improved the placement of the components and the cards organization, to make the product less sensitive to electromagnetic interference. This largely improves musicality and audio performances.

This Pro-Ject Maia S2 offers a maximum output power of 38W under 4 ohms. It is adapted to rooms of about 25 m2, by associating it with high quality Hi-Fi speakers that do not have a too low output (88 dB as minimum).


Associated with a good pair of speakers, this Pro-Ject Maia S2 all-in-one gives a dynamic and very balanced restitution on all its inputs.

The USB input, used with a computer that delivers uncompressed files, gives good results.

Like its predecessor, this Pro-Ject Maia S2 integrated amplifier is really bluffing. It can amplify a lot of analogical and digital sources. It is extremely rare that an all-in-one offers a quality phono input!

Today, it is still without competition! Highly recommended!
