Puccini U-Clock also features a USB-to-S/PDIF converter, which lets owners play high resolution audio from a computer through the legendary dCS Ring DAC™ inside the Puccini.
- Four Word Clock outputs further reduce jitter and improve sonic performance.
- Asynchronous USB input allows direct connection of a computer audio source and supports high resolution files up to 192kS/s PCM, and DSD in DoP format.
- Isochronous and asynchronous USB mode prevents the source injecting jitter into DAC.
- High-grade aluminium chassis and laminated acoustic damping panels reduce magnetic effects and vibration.
