I owned the stock SONOS connect and did not bother to try any mods since I upgraded to Aurender N100H.
I am not sure W4S / SONOS upgrade worthwhile unless you're able to take advantage of high resolution MQA albums now available through Tidal. Last time I checked, I did not see MQA albums accessible on SONOS app. You have a very nice DAC, I would pair with a streaming device that will allow you take full advantage of its capabilities.
I would recommend Aurender or Blusound Node 2 / Vault.
