Pro-Ject CD Box S2 (Open Box)



CD Box S2 – Compact CD player for high-quality CD playback in elegant S2 optics

CDs continue to lose in importance and are being replaced by modern streaming services. Still, not everybody wants to give up listening to a few of their favorite silver-discs and is now looking for a modern solution to put them on from time to time. Most people don’t want to invest into an overwhelming high-end player. They are looking for a small and handy, but still visually appealing system that will play their CDs at a high-quality level.

The CD Box S2 is the ideal Compact Pro-Ject CD Player. Ultra-compact, with a new carefully manufactured high-quality all-aluminum case, and buttons. There’s not much competition in this segment and it has ex­cellent sound-quality too. The drive in the Pro-Ject CD Box S2 enables 1:1 bit-accurate CD play­back. Compared to its predecessor, the CD Box S, the inner workings of the CD Box S2 have been technically revised. The player is controlled by a mini-computer; to optimize the PC-drive for a 1:1 bit-accurate rea­ding of the “Redbook” CD-standard and achieve a mo­dern audiophile playback solution. The CD is read into memory allowing any reading errors to be correc­ted, which ensures the best sound quality you can get from a PC-drive. Although this approach results in slightly higher start-up and reading times, it enables us to fit an audiophile grade CD player into the ultra-compact and beautiful S2 case.

A new and advanced DAC-chip enables a more precise and detailed digital to analog conversion. A new feature is the ability to switch between digital IIR and FIR filters. FIR filters are more complex DSP-operations and require more computational effort, however, they enable a finer and linear processing of the digital signal. The ideal base for even better sound! For even more versatility and no limits towards the top, the optical digital output can feed an external DAC. This way, you can let your favorite high-end DAC convert the accurately transferred bitstream from the CD.
