Pro-Ject Pre Box S2 Digital Edition 23 - DAC / Preamp
Tax included. Stock information
The Pre Box S2 Digital, first released in 2017, has gained significant recognition in the DAC market, particularly among digital and PC-audio enthusiasts. This acclaim stems from several factors, including its custom and proprietary clock design, meticulous PCB layout with separate power supplies, dual differential ESS DACs, and an exclusive digital filter that ensures pristine and transparent transient response. Despite its compact size, the Pre Box S2 Digital is considered a pinnacle of design in its category.
The chip crisis of 2020-21 significantly impacted the Pre Box S2 Digital due to its high demand. However, this downtime provided an opportunity for key improvements and refinements and as a result he product was rejuvenated nearly five years after its initial release.
Edition 2023 Improvements
New Internal Power Supply Design:
Enhancements to the power supply units (PSUs) for the clock, DACs, and analog output stages offer better isolation from PC USB power noise. Achieves a wider and flatter output impedance across the entire audio bandwidth.
Redesigned Master Audio Clocks:
The discrete audio master clocks have been redesigned to lower phase noise and enhance jitter performance.
New Output Stage with Higher Class-A Current:
The analog output stage, based around the SABRE9603Q, now operates with a higher Class A current. This improvement benefits performance with low impedance headphones and long cable runs.
New Headphone Amplifier:
The design is now more energy efficient with a 12% reduction in PSU current. The higher Class A analog stage operating current results in lower distortion with low impedance headphones. Users with mobile devices or laptops will benefit from the lower power draw while experiencing improved sound quality. 
Unbeatable Value – Handmade in Europe:
By minimizing cabinet size and standardizing casework across product lines, Pro-Ject reallocates production costs towards higher quality PCB design. The Pre Box S2 Digital Edition 2023 is meticulously designed and handmade in Europe, featuring a timeless design and durable aluminum casework.
The updated Pre Box S2 Digital Edition 2023 continues to deliver exceptional value and performance, solidifying its status as a top-tier DAC in the market.

Testimonials
Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.
The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.
