After studying different tests, I chose this one DAC rated for connecting an Apple TV3 to my HiFi. I am delighted with this purchase! The case is surprisingly small but very beautiful manufacture, easy to use and above all sound quality is at the rendezvous. I'll bet it will be even better after a break of a few tens of hours of use. I use AirPlay from my Mac or my iDevices to spread my music (or sound from my TV) to my HiFi and it is a great comfort. And when you consider that Apple TV only allows the 16bit / 48kHz output, it can be assumed that the quality of sound will be even more surprising with 24bit / 192kHz DAC as permitted it. Product frankly recommended for its excellent quality / price ratio.
