Summary: The sound is wonderful. We have enjoyed listening to streaming audio from the Internet and played over our ... NAD ... stereo system. The problems began shortly after installation, however. My Internet connection banged out unceremoniously. Yes, I read the reviews and knew that could be a problem. But, I have wireless N and a wireless N router, right? Should be on 5GHz, no problem. No, it's on the 2.4GHz band and it is a major problem.
Pros: Sound quality is excellent. Very few drops in streaming, once you establish a good connection that won't bang out the wireless network. I was able to find a longer USB cable in my junk box. Getting the transmitter several feet away from the computer helped stabilize the wireless network most of the time.
Cons: The wireless network issues can be frustrating. When I called Crutchfield tech support, the answer that I received was, "Bummer. You bought a product that transmits on the same frequency as your wireless network. Sorry about that." I'm quite certain that I'm not the first person to have this problem, and some things that worked for other folks might have been helpful.
Summary: This device, for someone like me who likes to explore different kinds of music and artists, is a must. There is no discernible lag from laptop/desktop to my hi-fi system. If you have interference issues, you can switch between the different channels this devices operates on. I feel that for their original MSRP they could have used 5 GHz band instead of the universally used 2.4 GHz band. The MSRP for this device is ridiculous. No wonder they decided to drop the price.
Pros: Build Quality Low interference/ability to switch channels
Summary: Was a little skeptical about it at first. Product comes in a box with a simple diagram of how to use it on the box, but no documentation inside. Was instantly recognized by my PC as "USB headphones," but was not clear how to get it to work with my J. River Media Center v. 17 with anything other than Direct Sound or WAV out (which limits sound quality). After some digging, tried ASIO4ALL (free software), which recognizes the "USB headphones," and will play to them.
Pros: Very simple, sounds good, pretty good range.
Cons: Poor, well no, documentation, no online support at NAD, have to research to find out how to use ASIO for it.
