I just set up a new Echo Gen 4, and My Media is working flawlessly with the unit. We're having no streaming problems or glitches. The audio quality of the Echo 4 is quite an improvement over earlier models, with a decent 3" woofer, and stereo front-firing tweeters. It can get
loud when cranked!

Just wish we could have a table full of people over the holidays to enjoy it together.
