The new Pro-Ject Pre Box S2 Digital Edition 2023 is based on the audiophile ESS Sabre ESS9038Q2M DAC chip and is designed in a dual mono concept. The component is capable of decoding digital PCM streams with a resolution of up to 32 bits/768 kHz and DSD up to DSD512. The MQA format is also familiar.
The Pro-Ject Pre Box S2 Analogue is a compact preamp designed to work with analog signal sources. The model provides high-quality sound with minimal noise and distortion. The preamp has three line inputs: two on the RCA connectors, and one on the 3.5mm mini–jack connector.
