Positive:
The pair sounds good, I came from a much larger (older) stereo component setup looking to keep the HiFi sound but also have some of the always on convenience that I have found using the numerous PLAY:1s around the house. I now find myself listening to much more music as the amp is always on ready to go.
It also sounds good for TV/Movies using ARC (with my previous setup I always found the voices too quiet and i didn't want a large AVR) even with just having stereo speakers - I feed the amp Dolby 5.1 from the Apple TV4, the Amp down-mix very well to include a DSP centre channel (this sounds noticeably clearer than feeding stereo), I am looking forward to adding rear surround at a later date.
Hardware is built well, and i think the cost is reasonable - especially compared to over HiFi components.
Negative:
I am having a few issues with the remote, sometimes when changing volume, the sound changes normally but the volume OSD lags and sometimes doesn't move at all. I also checked within the Sonos app, and it does the same. I change volume and it will lag and the slider will jump to the new volume setting.
Requests:
Id prefer to have linear volume control rather than a curve, at the moment my volume is mostly set at 50% to achieve good sound. I have read that most of the power is reserved for after 50%. (Source: theverge) and this is noticeable, with lower efficiency speakers.
Id really like to either see TruePlay or even better a parametric eq/convolution ability on the amp. With everything in one box I cannot add third party room correction, so this would have to be a software add-on. This would really complete the package.
On to the Frequency Response Graphs
(Blue) LS50 + Sonos Amp (Ports Plugged) - fairly flat response, note no treble boost/brightness
(Yellow) Loudness Setting On - taken at 50% volume subtle tapered 2.6db boost to bass and treble frequencies
(Purple)Crossover (80hz)
I've seen some reports that turning on the subwoofer crossover makes the sound overtly bright - i thought id investigate.
The crossover works correctly sloping the output at 80hz however it does boost the overall sound 3db, the response above 80hz is the same just louder, the volume setting wasn't touched between taking the measurements.
(Red)Crossover (80hz Reduced 3db)
I reduced the volume 3db, this was 7 pressed on the volume slider
That's better, as shown the crossover setting doesn't make the sound bright, it just boosts volume. I'm not sure why, perhaps because of the lighter load Sonos is happier to increase the volume.
Thanks for reading, if you have any questions or want me to go into any more detail please let me know.
Any HDMI source should send audio to the TV. It’s the electronics in the TV that “reflect” the audio back along the ARC. Apple TV is a normal HDMI source.
I’m confused. The article says essentially that the Apple TV doesn’t have ARC, that a TV set is necessary to create the ARC channel. The Apple TV doesn’t have the capability to create the ARC signal.
It doesn’t need to create it just work with it which it does.

I’m using the AMP with Revel Concerta 2 speakers and Sonos sub.
Are you talking about the Apple TV remote? I have no issues with volume control.
The only speakers that can Trueplay with the Amp are Sonance architectural which are designedI think there would be a market for indoor Trueplay tunable speakers but nobody seems to have jumped on that yet.

Apple TV does not do ARC, as it is not a TV (despite the name). To use ARC you connect your source devices to your TV (or receiver), and use ARC on that device to the Beam.
It’s not accurate to say ATV doesn’t support ARC just that it doesn't normally need to.

.. feed the amp Dolby 5.1 from the Apple TV4..
I'm considering a Sonos AMP for my KEF LS50's and found this post very useful.
But maybe a noob question, did you connected the AMP via your television HDMI ARC or directly to your Apple TV 4k and if so, how would you get any images from the Apple TV to your television, since the Apple TV only has 1 HDMI ARC port.
Thnx in advanced.

Hi Oeds de Meer,
I think my phrasing above might be confusing, as the other posters have said the chain would be
Apple TV > TV > TV HDMI ARC OUT > Sonos AMP.
What i mean by “feed the amp Dolby 5.1 from the Apple TV4” is set your Apple TV settings to Dolby Digital, also set your TV digital out settings to Dolby Digital or Surround as well. This will pass this signal through the TV to the Sonos Amp.
I have found - even only when using Stereo speakers that this sounds best as the Sonos Amp does a great job of down mixing.
Regardless of which speakers you choose, i would recommend the Sonos Amp and Apple TV combo, everything works well and dialogue is clear.

Amp is designed to receive input from the HDMI-ARC connection on the TV. The TV is then used to switch between sources.
Apple TV does not do ARC, as it is not a TV (despite the name). To use ARC you connect your source devices to your TV (or receiver), and use ARC on that device to the Beam.

I have found that the biggest drivers of sound quality are - given a certain standard of speaker quality that need not cost an arm and leg - where the speakers are placed and the room acoustic - after all, what you hear is a function of how the room interacts with the sound from the speakers.
As interesting as the first post is, it is *not* a frequency response test of the amp. It is a frequency response test of the amp + speakers together. (And, if you want to be a stickler, it's measuring the room too.)
This is correct, if it helps I would consider my room to be a "bright" room - minimal furnishings, laminate flooring (with a thin rug), no acoustic treatment.

I agree it's frustrating that the online reviews (at least the ones that I've read) don't include lab tests of the amp, as they would have in years past, when the major audio magazines had far larger circulations (and presumably larger budgets).
This brightness issue has made me hit pause. I was planning to purchase two Amps, but I'll wait and see now.
I agree it is confusing - whilst you can access the crossover settings and turn on without a Subwoofer attached it wont do anything, you need a Subwoofer connected for the crossover to be in effect. Failing that you can just plug in a RCA cable and this will fool the amp into thinking that a sub is connected. I queried this with the Sonos team and my own testing to confirm.
I've seen some reports that turning on the subwoofer crossover makes the sound overtly bright
How is it that those hearing a brighter sound and alleging the amp to be the culprit never post any graphs?!
On the Sub - can the crossover be turned on without anything plugged into the Sub Out jack?
