I initially bought this so that I can have bluetooth in Zone 2 (outside for me). But my receiver can only send analog to Zone 2. This is common unless you have a really high end receiver that can send digital/HDMI audio to Zone 2. This bluetooth adapter is for a digital connection only unless you buy an additional digital to analog converter. I wound up keeping it because I will still use it indoors (Zone 1) but I had to buy another bluetooth receiver that had analog connections (HomeSpot NFC) so I could have bluetooth outside. If you can have a digital connection for all of your bluetooth needs, then this one will work for you. If you need analog, look elsewhere. I am giving this 4 stars because for this price it should include connection capabilities to analog and not be limited to digital.

I just started subscribing to Google Play Music and needed some way to stream the music to my Yamaha RX-V773 (but it will work with any device that accepts a digital coax connection). I wanted a coax digital connection and the AptX codec. Setup was a breeze. I compared my HTC one that supports the codec and my Dell PC that does not. There is a substantial difference in the two – but it only became truly apparent when using the Pure Direct mode and was really noticable when I used it with an external DAC. I think digital coax sounds better (I know they are just ones and zeros – but jitter matters), but if you don’t care or want optical instead, you might check out the NuForce BTR-100.

This dock outputs digital audio where the YBA-10 Bluetooth & YDS-12 Apple Product dock only output Analog audio. This dock doesn’t require a special connection to your receiver or other audio equipment. It only requires digital (coaxial) RCA connection along with 5 volts through a USB connection. A USB charging cube is excellent power source for the YBA-11.
