Finish:

The Pre Box RS2 Digital is a class-leading pre-amplifier, DAC and headphone amplifier with an ultra-linear signal path and ultra-low noise. Boasting a host of connection options, it is the ideal system hub for driving high-end headphones, power amplifiers or active speakers. 

The 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.

Key Features:

  • Luxury pre-amplifier with DAC and headphone amp features
  • Dual Mono ESS Sabre DAC chip configuration
  • Multiple digital inputs, including wireless Bluetooth connectivity
  • Full MQA support over USB and when connected to a CD transport
  • Roon Tested, for easy set-up in a Roon system
  • Extensive digital filter options built-in
  • Fully-balanced dual mono design for absolute audiophile performance
  • Output stage switchable between 6922 tubes and solid state signal paths
  • High-quality headphone amplifier stage optimised for high-end playback
  • Ultra-linear and ultra low noise design throughout
  • New high-quality display with responsive and fast UI design
  • Aluminium IR remote included 


The analog output is a buffer that is both solid state and high-quality tube. Thus, the customer can choose which of the option 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).

In 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).

The 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.

A premium full aluminium remote control is included in the packaging and the Pre Box RS2 Digital is available in a high-quality silver or black aluminium case. The big display screen on the front shows all relevant information in an easy to read, clean and structured way. Navigating the menu is very responsive and fast, allowing you to set up the unit to your preferences in seconds!

The Pre Box RS2 Digital is equipped with a large LCD display that matches the CD Box RS2 T design. Control is best achieved with the supplied aluminium IR remote, where the extensive setting options menu can be navigated with ease. The Pre Box RS2 Digital is a truly complete solution, and is available in high-quality aluminium black or silver finish.
