Thank you for purchasing this Pro series iDSD. 

The Pro iDSD is a 'state of the art' reference digital to 

analog converter. lt is able to excel in many scenarios - as a wireless hi-res network player or the central 
DAC in an expensive high-end home system, to quote just two examples.  The on-board balanced 
headphone section means high-end headphones can also be directly connected to it.

Features:

1.  Quad-Core Burr Brown MultiBit/DSD hybrid DAC supporting DSD1024 and PCM768kHz
2.  Studio grade DSD1024 remastering (Crysopeia FPGA Digital Engine)
3.  Wireless DLNA/Airplay™/Ethernet Hi-Res Playback
4.  User-selectable analogue stage: Tube or Solid-State
5.  Master Quality Authenticated (MQA) playback

  6.  Global Master Timing femto grade clock system with external clock input options

        7.  Five  lters: Bit-Perfect/Bit-/Gibbs Transient Optimised/Apodising/Transient Aligned

  8.  Fully discrete passive LC analogue  ltering

        9.  Zero Jitter Memory Buffer and Galvanic Isolation for all inputs

 10.  Discrete headphone/line ampli er
 11.  Balanced inputs and outputs

    

 12.  Galvanic isolated ultra-quite power supply with super capacitors
