Improve ARC ultra w more speakers? I am underwhelmed with the sound with my new Samsung TV.  Dialogue ( especially) females seems " brittle" and thin. Music not as good as reviews have stated. Anybody have this issue and then added ERA100's or a sub ? Dont want to go deeper $$ if this won't improve greatly.  btw - have tried every setting possible in app but can’t tell much difference in any setting. Sorry I did not live 1st  more bars 1st.

Couple of things to check, first.

  1. What type of signal is being sent from your TV to the Sonos Arc Ultra (ARC is a different ‘thing’, and stands for Audio Return Channel, usually)?
  2. Make you’ve either run, or turned on TruePlay. 
     

Adding dedicated surround speakers and a Subwoofer certainly offloads some effort from the Arc Ultra, which may make a difference. It does depend on 1. above, however. If your devices are sending a stereo signal to the Sonos, it won’t make much of a difference. Make sure you’re testing with / sending at least a Dolby 5.1 signal. Some talking heads and sports events don’t always use the full capabilities.
