Why should it jump to 87 dB at 5 watt?
Maybe I'm missing something, but shouldn't it be 87dB at 5W to match this (level 3 numbers). 68dB at 5W matches the level 2 numbers.

This graph is for max power versus nothing. It is not related to 5 watts. I think I am still not understanding what you are saying.Maybe I'm missing something, but shouldn't it be 87dB at 5W to match this (level 3 numbers). 68dB at 5W matches the level 2 numbers.
I checked the project file and the graph is definitely the one with level 3 as I have set the max to 2 volts (otherwise it had to be 2.5 volts). I could re-measure the same graph using different input settings to verify what is going on. But that requires me unpacking the unit after I cleaned and boxed the unit up. Are you going to put me undoing that?Well, it will not surprise me if I just don't understand something. However, this is what I mean. Looking at the THD+N number at 5W on the graph, I get about -68dB. I would expect this to be close to the measurement in your other SNR test, at least for a case like this where noise is dominant over THD. So I would expect the graph to agree with the level 3 SNR measurement (87dB). Instead, it agrees with the with the level 2 SNR measurement (68dB).
No, no need for that. But perhaps help me understand if something is wrong in my thinking with expecting the graph to match the SNR @5W measurement.I checked the project file and the graph is definitely the one with level 3 as I have set the max to 2 volts (otherwise it had to be 2.5 volts).

The one thing I can say is that SNR test is stand-alone and many things impact it so don't use that for anything. The downward part of the slope may be noise dominated but also has a distortion component. It is not clear what the higher gain settings do. Perhaps they increase distortion.No, no need for that. But perhaps help me understand if something is wrong in my thinking with expecting the graph to match the SNR @5W measurement.
Kind of. The power measurement graph skips steps so may not match with the 5 volt setting I use in the dashboard.What if we compare SINAD number @5W to the THD+N shown on the graph - shouldn't they match?
SNR is measured at or near max power, not 5 watts.the Analog Level 2 test of SNR @5W just seemed unlikely to be a coincidence.
That explains it, and then agrees with the graph. Sorry about the confusion!SNR is measured at or near max power, not 5 watts.
That's the output I tested by putting the line out in full range mode. Is this what you are asking?Would it be possible to test the subwoofer output? Curious if there is a crossover built in to the output, or if upper limit is capped in the app.
No, the performance is dominated by noise. It may have something to do with the programmable input they have.Any idea why the line inputs perform significantly less than streaming? Was it clipping perhaps, with a 2V signal and the gain setting chosen in the app?
The HDMI is a "roach motel." Signal goes in, nothing comes out. There is only one HDMI port. Usually these are pass-through which would let me run my tests. But it is not. I am assuming it captures the audio from it and that is that.Also does the HDMI route audio through the DAC, or is a simple pass through direct through the digital amp?

So true. I hate the current tablet interface of Sonos. The old layout was much better. Good thing Sonos left the PC/Mac interface unchanged and that's all I use now to operate my Sonos Connects. The last time I bought a Sonos device was more than a ~decade ago. My Sonos Play-1 stopped working and I don't plan to replace it with another Sonos. The Amazon/Google devices are more functional and cheaper for garage duty.
Oh wait, I got my reviews mixed up. I thought we were in the NAD 7050 thread.Hmm, so your test output (into the AP) was coming off the subwoofer OUT? Is that the only audio lead that you could test off off (to test the DAC)?
My situation exactly. I have left behind the Sonos and switched to Amazon for my woodshop.
