      Perfect streamer

      has all the outputs that I need for my application that send out all at once. Sound is clear with better bass than I would if connect my phone or iPad via Airplay or Bluetooth directly to my Onkyo that costs 1k. I had a party and some friends notice better sound in system. Bluetooth connection is solid better than the Wiim that I had before I returned and would cost more than this unit.

      Blafili B3 Incredible Performance

      I just received the Blafili B3. I hooked it to a vintage Sansui AU-717. The sound of the Blafili is incredible. Very high quality, dynamic, excellent stereo imaging. Tested with Qo-buz source. Value to money product, highly recommended

      Works Great

      Very happy with my blafili B3. The sound quality is superb and bluetooth range is exceptional. We installed in a gymnasium and have no connection issues anywhere in the facility. The team at blafili was very helpful assisting me to find a device that had long range and a security PIN. I even got a custom broadcast name. Very happy with my purchase.
