In excellent condition, with everything in the original packaging.

I connect my laptop through usb and my ps3 using the toslink input. I also use it with power amplifier for my speakers. It's really convenient and saves space. One of the best dac/headphone amps.
 
  1. Balanced and unbalanced analog inputs
  2. 24bit/192kHz digital stereo inputs- AES3, S/PDIF, TOSLINK and USB
  3. High speed USB interface - completely asynchronous transfer mode allows for bit-perfect playback with zero interface induced jitter
  4. Driverless operation on Windows & Mac up to 96kHz/24bit
  5. Supports USB Class 2 audio specification for 192kHz/24bit operation on Windows & Mac (drivers needed for 192kHz operation under Windows)
  6. New generation DAC's and ultra low noise balanced current to voltage converter yields more musical performance compared to the m902
  7. Mono mode for checking mix phase issues (or listening to Pet Sounds)
  8. s-Lock™ phase lock loop sample clock regeneration for ultra-low jitter and rock solid digital stability
  9. High-current transimpedance headphone amplifier circuitry built to effortlessly drive low impedance headphones
  10. Balanced and unbalanced variable level analog line outputs
  11. Improved power supply architecture isolates headphone power amplifiers, line amplifiers, DAC's and digital logic
  12. Precision level control with a 99.5dB range in 0.5 dB steps
  13. Channel level matching accuracy of 0.05dB
  14. Improved x-feed circuit eliminates perceived loss of low frequency content
  15. Optional infrared remote control available
  16. Internal linear power supply with custom wound toroidal transformer

​Collection in Birmingham or £20 postage within the UK
