The ZEN Stream comes with all accessories and OVP and additionally I got a better power supply (iFi Audio iPower 15 Volt) which is included in the bundle.
The latest firmware is installed and the device has already been reset to factory settings.

I am the first owner, pet-free, non-smoking household, everything in mint condition and fully functional.

I'm located in Germany, if you from Germany insured shipping is included in the asking price, for other countries I need to check the prices with DHL.
