Pro-Ject DAC-Box DS2 Ultra - High-End DAC Hi-Res/DSD

• Top grade DAC
• 6 Inputs: 1x USB, 3x optical (TOSlink®), 2x coax (S/PDIF)
• Full metal casing in silver or black

The DAC Box DS2 Ultra is a true high-end digital-analogue converter, with optimal fidelity and a wide feature set for use in almost any digital hi-fi system.

Built around the premium Asahi Kasei Microdevices AK4490 DAC chip, the DAC Box DS2 Ultra works with digital signals up-to 32-bit / 768kHz and DSD256 (DoP). The additional AK4137EQ sample rate converter with Velvet Sound technology up-scales all signals to 768kHz for minimal signal loss and enables the built-in filters (5 to choose from) and sound modes (3 to choose from) to have a greater impact. With this chip set configuration, the DAC Box DS2 Ultra can deliver the same rich, musical sound-field, with accurate bass reproduction and minimal distortion, as the superior Pre-Box DS2 Digital

The DAC Box DS2 boasts six digital input options. The two coaxial and three optical inputs are limited to 24-bit / 192kHz signals, where the more advanced signals are reserved for the Type-B USB input. The USB input utilises asynchronous USB technology, based on XMOS designs, for playback of high-resolution files. This high-resolution coverage spreads to 11.2MHz DSD256 files, where the design of the DAC uses DSD Direct Path for un-modulated signal transmission (DoP).

Operation of the DAC Box DS2 Ultra is effortlessly simple via the clearly marked front-panel controls. Internally, it boasts the same 4-layer PCB boards as other DS2 products, and the output stage is configured with solid-state Class A circuitry for added analogue warmth and low output impedance.

The DAC Box DS2 Ultra is a real high-end offering for digital audio enthusiasts who demand the most from their hi-fi equipment.
