1. Great sound and easy to use
Connected through TOSLINK and paired to iPhone immediately. Sound through Yamaha Receiver and Energy Connoisseur speakers is excellent. It is quite expensive, but quality and performance is better than expected.

2. Excellent (but pay attention to the D/A switch.
I bought this a couple weeks ago and it will fit the bill perfectly. MAKE CERTAIN TO SWITCH THE DIGITAL/ANALOG SWITCH ON THE BOTTOM OF THE UNIT (I of course did not read the instructions). I use it in the garage and outside at the pool. When the neighbors come, all they have to do is Bluetooth connect; it turns on the AMP automatically and they have music without having to get into my house.

3. Excellent product
Very happy with this bluetooth receiver. Sounds excellent and setup couldn't be simpler. Only complaint I have is that the blue LED is way too bright and unnecessary in the first place. Otherwise this is perfect for my needs.

4. Bluetooth Excellence
I bought 4 different Bluetooth Receivers that are now just sitting around. I'll find use for them but not on my main system. My speakers are the Magnerpan 3.7 and if you're familiar with them you'll know the kind of equipment you need to drive them properly. I hooked up the Parts Express Bluetooth to my Processor through tos-link to let my processor's DAC take over. I was stunned by the quality of sound I heard. The other ones, and some more expensive did not sound anywhere as good. If you hook those up to mediocre systems you would probably say they sound good. For he money and of course a good DAC these are your best bet. I love it.

5. Great Little Box
This little gem is exactly what I was looking for. It works perfectly and is small enough to fit anywhere in my sound system. I haven't tested the Bluetooth range but it works great in my application. Just be aware of the audio switch on the bottom. You can select digital out or RCA out. Mine came with digital selected & I was using RCA so it fooled me for a moment.
