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.
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.
The Pro-Ject Media S3 integrated amplifier impresses at first glance thanks to its premium aluminum housing. It not only gives the model an interesting look, but also allows you to eliminate interference and make the operation of the MaiA S3 more stable. The amplifier's circuitry is based on the dual mono principle. A motorized Alps potentiometer is used as a volume control.
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.
