Anyone listen to Pandora lately?

No!

No!

Also listen through Sonos and find the SQ on Pandora unremarkable.  However, there are reasons it may sound better than it used to.

If you've added zones, it's possible that your network has gotten "meshier" (strange word), which really does help SQ as the periodic brief signal drops get less frequent.  Sonos networks perform much better in my experience when the number of zones per area covered is increased.  You can also achieve this with zone bridges between distant zone players.  More players Absolutely IME getting helps SQ.

Used to be if you paid for Pandora and eliminated the commercials it also benefitted from higher resolution (seems true, and worth the 5 cents a day). I think it sounds fine on my rig, although I prefer CDs and vinyl of course…I use it in my car also, and for that it’s great.
