Know before you buy
You can connect up to three devices simultaneously using the USB B, optical (TOSlink), and coaxial (S/PDIF) inputs. This allows you to easily switch between sources like a computer, a CD transport, or a television.
The USB input offers the highest level of performance, supporting PCM files up to 32-bit/768 kHz and DSD256. While the optical and coaxial inputs are excellent for standard high-resolution files up to 24-bit/192 kHz, the USB connection is required to unlock the full potential of the DAC.
The five digital filters allow you to subtly tailor the audio output to your personal preference or the specific recording. This includes a proprietary transient filter designed to provide a more natural, lifelike sound profile.
Yes, it features a standard RCA line-level output, making it compatible with almost any integrated amplifier, pre-amplifier, or active speaker system.
The robust aluminum and metal construction serves two purposes: it provides a sleek, durable aesthetic and, more importantly, acts as a shield against electromagnetic interference and vibrations that can degrade audio signal quality.
The DAC Box S2+ is powered via a 5V micro-USB connection. You can power it using a standard USB wall adapter or by connecting it to a clean power source like a dedicated USB power bank or a high-quality computer port.
