Σε συνεργασία με έναν από τους κορυφαίους σχεδιαστές ψηφιακών συστημάτων στον χώρο, τον John Westlake, το αρχικό Pre Box S2 Digital εξελίχθηκε σε μια πραγματική audiophile ευκαιρία, ικανή να ανταγωνιστεί προϊόντα πολύ υψηλότερης κατηγορίας τιμής. Improved 2023 edition of a Modern Pro-Ject Classic The Pre Box S2 Digital – since its release back in 2017 – has quickly ascended to an exceptional status in the DAC market and gained a reputation among digital and PC-audio enthusiasts for its remarkable ability to compete way above its price point. This achievement can be attributed to a combination of factors, including a custom and proprietary clock design, meticulous PCB layout featuring separate power supplies, dual differential ESS DACs, and an exclusive proprietary digital filter designed to deliver pristine and transparent transient response. The Pre Box S2 Digital may seem small, but it is really the ultimate design. The chip crisis of 20/21 has hit the Pre Box S2 Digital particularly hard, given its enduring demand. But during the downtime, we and original designer John Westlake seized the opportunity to implement key improvements and refine the design, thus rejuvenating the product almost exactly 5 years An audiophile bargain Working with one of the best digital designers in the industry, John Westlake, the original Pre Box S2 Digital has become an audiophile bargain, able to compete with products way above its price. The reason is John Westlake’s outstanding PCB and proprietary clock cir- cuitry design. Digital audio is the art of time, with our new proprietary clock design we have managed jitter rates of unrivalled 100 Femtoseconds, this easily outper- forms many renowned and respected audiophile clock generators!
