It uses the same excellent sounding DAC chips as the S2 version, proving once again that the Pre Box S2 Digital was already at the very top of high-end DACs and absolutely beyond its competition. Based on the same core-design principles, the feature set is extended and driven to new heights. The result is a fantastic sounding and very versatile box. The perfect partner for the cream of the crop of high-end amplifiers and speakers alike!\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eThe Pre Box RS2 Digital is a DAC and preamplifier that uses a dual-mono configuration of the highest-class D\/A converters from ESS Sabre. ESS9038Q2M chips provide the highest sound quality in price-affordable, high-end circuits. Unlike most of DAC´s in this price range, the Pre Box RS2 Digital includes dual DACs and separate signal paths for the left and right channels. Also thanks to these converters, the Pro Box RS2 Digital supports up to 32-bit \/ 768 kHz files in PCM and DSD formats (up to DSD512) via USB, covering any digital file you can buy or stream.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eThe analog output is a buffer that is both solid state and high-quality tube. Thus, the customer can choose which of the options is preferred. The Pre Box has eight digital filters. One of them is the proprietary optimal transient digital filter from the MQA creators. With these filters, the listener can customize the sound to suit their own preferences. Pre Box RS2 Digital comes with full HW and SW support for MQA technology (Master Quality Authenticated).\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eIn the Pre Box, the USB input signal is processed by a powerful multi-core XMOS microcontroller with advanced Multi-Core RISC architecture. The CPLD MAX II (Complex Programmable Logic Device) Altera is used for re-clocking, which together with the XMOS microcontroller brings high-quality processing of both classical and MQA technology. For the ideal use of this technology, it is best to connect the Pre Box to our Stream Box S2 Ultra in conjunction with the TIDAL service. You can also enjoy MQA quality by linking it with our new revolutionary CD transport, the CD Box RS2 T. The CD Box RS2 T can be connected to the Pre Box by reliable I²S differential bus via the HDMI connector where the Pre Box RS2 Digital also provides the master clock (16.9344 MHz).\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eThe headphone amplifier is the ultimate design. No compromise. No coupling capacitors. Not even on the output. All of the the amplifier is DC coupled. A very fast DC servo assures no DC voltage on the output. Its output power is suitable for all kind of headphones.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eA premium full aluminum remote control is included in the packaging and the Pre Box RS2 Digital is available in a high-quality silver or black aluminum case.
