   Roksan  - Reference DXP SE
    The DXP SE is a no compromise MM and MC Reference phono amplifier     designed for use in the finest analogue systems. The amplifier's     complimentary, fully symmetrical Dual Mono design improves channel     separation, distortion, signal to noise ratio and accuracy whilst     maintaining the purity and coherence of the audio signal.

    The Reference DXP SE uses the DX2 System Platform. The DX2 can     house the Artaxerxes.X reference phono module, the XPS.V reference     Xerxes Motor Drive module and the DC Power modules needed to power     them. There is a standard and reference DC Power module to choose     from.

• Mains Input: Filtered, double fused, switched IEC
• Transformer: Ultra low noise internally and externally shielded 350 VA Toroidal
  
• Power Source:
  • 100V - 120V: 50Hz / 60Hz
    
  • 220V - 240: 50Hz / 60Hz

  There are eight options available on the DX2. The DX2 can be configured as being only a DC power supply of ±26 Vdc,   (powering Roksan DC powered products), to a fully loaded XPS.V / DSU plus Artaxerxes.X / DS1.5 (i.e. Xerxes motor drive   and MM/MC Phono amp). The chart below outlines possible options and their package price.
