Pro-Ject's DAC Box S2+ compact digital-to-analog converter comes fully equipped to meet the highest audiophile demands. Performance is superb with high-res music files. It supports the playback of PCM files up to 32-bit / 768 kHz and DSD decoding up to quad DSD (DSD256). 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. Unwanted noise coming in through USB is double filtered to suppress it to a level where it can't affect audio. With organic polymer capacitors and thin film mini-MELF resistors, Pro-Ject was able to create a tiny device that will blow away even much bigger components for a much higher price. With five digital filters available onboard (including the proprietary Optimum transient digital filter), the sound can be shaped precisely to your liking. The new aluminum/metal casing ensures highest aesthetics and protects against vibration and interference! DAC Box S2 + comes in silver or black finishes. We offer a 30 day return for any reason. Buy with confidence!
