Pro-Ject DAC Box S FL
Non-oversampling / Filter-less CD-quality DAC with analogue character

Overview
The DAC Box S FL is a compact, non-oversampling digital-to-analogue converter designed to deliver warm, analogue-like sound from digital sources. With its NOS (Non-Oversampling) design and use of four TDA1543 DAC chips operating in parallel, Dual Differential Mode, it focuses on simplicity and musicality rather than ultra-hi-res specs.

Sound Character & Technology
By avoiding digital filters and upsampling, the DAC Box S FL preserves CD-standard 16-bit / 44.1 kHz resolution with minimal processing overhead. Its four DAC chips in parallel help reduce distortion in the audible range, giving a smooth, full-bodied sound and strong bass presence for many users who prefer a less clinical presentation.

Connectivity & Features
It offers both optical (TOSlink) and coaxial (S/PDIF) digital inputs, with a front-panel selector to switch between them. The analogue output is via a single pair of RCA jacks. The unit includes a standby mode, front LED indicators for power and input selection, and comes in either a black or silver faceplate.

Design & Build
The DAC Box S FL features Pro-Ject’s clean ‘S-design’ styling, with a minimalist metal chassis. It’s small and portable at around 103 × 36 × ~109 mm, weighs about 560g, and produces line-level output suitable for feeding into preamps or integrated amplifiers.

Why Choose the DAC Box S FL?
If you’re after digital sound with more musical warmth, less processing, and emphasised analogue character—especially from CDs or standard-rate digital files—this DAC is a strong, affordable choice that prioritises listening enjoyment over specs on paper.
