During the review period, I got comfortable using voice commands with Alexa to stream music from Tidal and Pandora to the Denon receiver or the HEOS speakers. It was a nice convenience to be able to dictate the music on the fly while cooking in the kitchen without having to grab the remote or my phone. And the full sound of the HEOS 5 was impressive for a speaker of its size. There were only two or three times when Alexa got confused, playing the wrong song or not playing a song at all. And it was great to have the two HEOS 1 speakers set up as a stereo pair in the bathroom to play music streamed from the HEOS app or directly from my phone while getting ready in the morning.
Streaming high-resolution music from my NAS was straightforward using the HEOS button on the Denon remote, too. The AKM DACs and amps built into the Denon did a more than adequate job resolving the 24bit/192kHz and DSD files I sent their way.
