    Fully Equipped for Cutting-Edge Performance

    Pro-Ject's Head Box S2 Digital headphone amplifier comes fully equipped for the highest demands of the modern audiophile. It supports playback for PCM files up to 32-bit / 768 kHz and DSD decoding up to quad DSD (DSD256). It also provides a significant upgrade from the anemic headphone section built into many conventional amplifiers and lets you add headphone capability to amps and other gear that lack a headphone jack.

    With five digital filters available onboard (including the proprietary Optimum transient digital filter), the sound of the Head Box S2 Digital can be shaped precisely to your liking.

    Connection to a Wide Range of Devices

    Three digital inputs ensure a connection to any source available, be it a personal computer via the USB B input or a TV set via the optical input. The coaxial S/PDIF input will accommodate a digital transport such as the Pro-Ject CD Box DS2 T. All inputs offer support for high resolution data up to 24-bit /192 kHz. The USB input offers full high-resolution support for all files up to PCM 32/768 and DSD256.

    The front-panel 1/4" headphone jack delivers a clean and precise sound with a musical touch. Noise coming in through USB is double filtered to suppress it to a level where it can’t affect audio, for undisturbed listening experience.

    Highest Quality Parts and Construction

    Only the best possible components were used to create this one-of-a-kind headphone amplifier. The aluminum/metal enclosure provides the highest aesthetics and protects circuitry effectively against electromagnetic interference and vibrations.

    Due to its low price combined with versatility, power and high quality sonics, the Head Box S2 Digital is an absolute audiophile bargain!
