Although I got a great Black Friday deal on this, I was hesitant to choose it over Sonos, which was twice the price. Overall, though, the reviews seemed pretty good, though. So, I gave it a shot. It didn't seem too bad. It doesn't look too bad and has decent volum, although the sound is a little muddy. I thought it would be nice to have the option of connecting via bluetooth, but that didn't turn out to be as convenient as I had hoped. I thought I might be able to use it with my Echo Dot and seamlessly switch back and forth between the bluetooth connection for the dot and wifi for streaming. Of course, that was wishful thinking. The application is pretty barebones. One of the limitations is that I can't listen to my personal library stored on Amazon's music service. A Denon support article says that's an Amazon limitation. Maybe, but somehow Sonos figured out a way around it. Also, only a handful of services are currently supported. I knew this going into it, but thought things would get better down the road, and they might. The real deal breaker, though, was the customer service. After two days, SiriusXM would no longer connect, so I opened a case with their "customer service" department asking if this was an outage. I received an out of office reply. Several days later, SiriusXM was still not working (although it worked from the native app). I still hadn't received a reply. So I did a search and found a bulletin on Denon's website apologizing for the outage. Soon after that, I returned the device. To this day (a month later, I still haven't received a reply from Denon's customer service. I did , however, purchase a Sonos Play 1. The quality of the hardware, software and services is so much better, it's astonishing. The sound is perfectly clear, more services, the software is more polished and can do things like play my personal tracks from Amazon. It's like night and day. I have read that the higher end Denon Heos devices have excellent sound and overall hardware. However, if they provide poor software and, worst of all, poor customer service, I really don't have any faith in their ability to compete with Sonos. I'm guessing the Heos line is not going to be around in a few years. Maybe they'll shape up and stay in the game, but based on my experience, I'm not willing to bet on it.
