Denon HEOS-AMP Wi-fi Amplifier for House Theater, Bluetooth Hello-Res Amplifier

Works great with Alexa
Just bought my 2nd one. I am using these to power my whole house speakers. Works great with my echo dots. I don’t use the heos app, 100% voice control with echo. Only thing I don’t like is when you link more than one in a group, you can’t use the group name in Echo. You can play the group by requesting any room in the group but that yields some odd results. So I have “kitchen” and “living room” grouped “downstairs”. If I request either living room or kitchen it plays on both. If I ask echo to skip a song, it asks whether I want to skip on the kitchen or living room. Minor. I am just stoked they integrate as well as they did with voice control. No special catch phrases to activate the audio. I junked my Bose amps and switched to denon due to similar specs but better usability

Great For Denon or Marantz Users
After using a ZVOX Soundbase as a Bluetooth speaker for years in my bedroom, I decided to upgrade the whole system to something I could both use for TV sound output and as part of a broader HEOS whole home (or in my case, small apartment) system. I’ve been using Denon receivers for a couple of decades now and got a HEOS 3 HS 2 speaker for my office several years ago. I was growing weary of the niggling irritations of using Bluetooth streamed from my phone as my only source and took the plunge to create an actual stereo system in my bedroom. I wanted to tap into usefulness of HEOS and this seemed like a good way to go since it meant I could use whatever speakers I wanted.Since I already had HEOS installed, adding this into my system was easy, just select the network and enter the password, or I could have used WPS, but that seemed harder than just entering the password. Once up, I entered a name for the amp, set it up on Alexa and I was good. I also hooked up the optical output of my Roku Select 32″ TV to it. Here is where the reason for a four star rating comes in. Unlike my AVR-X3400H in the living room, the HEOS Amp does not have an HDMI eARC input.No problem, I figured, I’ll just hook up the optical and should be good. However, the HEOS Amp does not have controls to control audio delay to help it sync up audio and video. Most TV’s have an ability to adjust the audio delay, but the very low end Roku brand TV I got is rather limited in the range of the adjustment. The adjustment is done using the Roku app, which automagically adjusts the sync. The only problem is that the adjustment procedure does not work exactly and left me with about a 2 frame delay between the audio and the video. The Roku app says to use the fine tuning control to adjust this, but there is no fine tuning control. That combined with the lack of the ability to set audio delay on the Amp leads to a situation where it is not really possible to get stuff to sync up. This is really on Roku and not Denon, but it does leave me less than happy with the final result.Overall, I recommend this if it fits your use case and if the TV you want to hook up to it has the ability to adjust sync manually. It sounds fine driving my Neumi Silk 4 speakers and the sound is fine. I’m also very happy to be able to use HEOS to stream audio rather than Bluetooth off of my phone. And of course, being able to fill every room in my place with music when I want to rock out and annoy the neighbors, nothing can compare!

This amp worked exactly as advertised, easy to set up great sound connected to all my wifi music and bluetooth devices.The only issue i have is it does not easily switch from wifi back to bluetooth, you have to continually re pair
