High Fidelity Listening Experience
Our audiophile analogue and digital circuitry is engineered for maximum signal purity and musical authenticity. The low-noise analogue design is carefully optimised with short signal paths to preserve dynamics, tonal balance, and fine detail without unnecessary processing. High-resolution digital sources are converted via a premium 24-bit/192 kHz DAC with precise internal clocking for low jitter and accurate timing, while strict separation of digital and analogue sections prevents noise from degrading the signal. The result is a clean, natural, and engaging sound that faithfully reflects the character of every source.
Versatile In- and Outputs
The Pre Box S3 offers all modern connectivity to act as your central Hi-Fi stereo hub. You can also connect digital sources like your TV via eARC or a CD transport via the coax or optical S/PDIF inputs and use the internal DAC with a quality up to 24bit and 192kHz. It also provides versatile output options. The variable RCA output is connected to your power amp. A seperate fixed line-level output allows you to forward the connected sources to your external headphone amplifier or second zone. Connect your subwoofer via the dedicated sub-output. Trigger connectivity for remote turn on/off is included next to a very versatile RS232 connector for custom installation remote control.
