The Pro-Ject Stereo Box DS3 is implemented in a dual mono concept. The output amplification stages are capable of developing up to 150 watts when operating on a load with a nominal resistance of 8 ohms. There is also a high-quality headphone amplifier, offering an impressive 450 MW of power for headphones with a resistance of 32 ohms.
ProJect MaiA DS3 is a new generation integrated amplifier with amazing sound and advanced technology. The device develops a power of up to 140 watts per channel and is compatible with floor and shelf acoustics of various brands. Up to 9 signal sources can be connected to the amplifier, including a vinyl player, a computer via USB, and mobile gadgets via Bluetooth.
To connect the sources, the novelty offers two analog inputs on RCA connectors. There is even a pre-amp output implemented on the 3.5mm mini jack connector. The amplifier develops 21 Watts in each channel when operating on a load with a nominal resistance of 8 ohms and 40 Watts at a load of 4 ohms. High-quality screw terminals are provided for connecting acoustic systems.
Despite the fact that the Pro-Ject Stereo Box E integrated amplifier belongs to the initial state of Hi-Fi technology, it stands out for its rich functionality – there is a DAC unit, a phono corrector for cartridges with a movable magnet (MM) and a Bluetooth adapter with support for the aptX HD codec for wireless streaming of high-resolution audio.
