The Pro-Ject MaiA DS3 (My Audio Integrated Amplifier) is a versatile, high-performance compact integrated amplifier and DAC designed and handmade in Europe. Delivering 140 watts per channel into 4 ohms via a dual mono amplifier layout, the MaiA DS3 provides high power and comprehensive connectivity within a full-aluminum chassis designed to shield internal electronics from mechanical vibration, radio frequency (RF), and electromagnetic interference.
The MaiA DS3 features a Texas Instruments PCM1795DB 32-bit/192kHz Delta-Sigma DAC alongside an XMOS asynchronous USB input supporting high-resolution PCM up to 24-bit/192kHz and native DSD up to DSD256. It offers nine total analog and digital inputs—including an MM/MC phono stage, line-level inputs, optical/coaxial S/PDIF, and Bluetooth 5.0 with aptX HD—alongside a built-in headphone amplifier, variable subwoofer outputs, and fixed line outputs.
