Hi all,
I’ve read that the Sonos combo adapter for the ERA 300 (which has both 3.5mm analogue and ethernet inputs) allows for direct streaming into the unit. I’m assuming that this should allow for better quality music, as only the only conversion would be via the unit’s internal D-A.
Does anyone have experience of this setup, and if so, have they had a notable improvement in music quality over Bluetooth 5, wi-fi 6 or 3.5mm audio input via Sonos adapter?
It would be equal, not better, than a WiFi connection. That’s the way Sonos is designed.
Wifi, any version, and Ethernet are going to give equally high quality, they deliver identical bits.
The 3.5 adapter is going to have an analog/digital conversion added to the above. How much impact it has isn't documented. Better or worse than the Port or other Sonos analog input is again undocumented.
Bluetooth, no clue, but based on other devices (not Sonos) it always remains my last choice. Digging into the connection details for the exact quality connection it will deliver between your transmitting device and your specific Sonos product might provide some insignt as to signal to noise, bitrate, bit depth and overall quality.
If you used the dongle’s network connection, quality would be the same as WiFi. Using the 3.5mm input would add another A to D conversion to the signal path. I suppose that there could be a discussion about the quality of an A to D or D to A conversion somewhere else in the path to the 300. Each conversation risks some loss of quality.
