We have two Sonos surround set-ups, one we use much more than the other, and I’m wondering whether to reconfigure to maximise the sound quality of the one we use most. 

Current set-up:

Room 1: Playbar and 2 x Play:3 

Room 2: Beam, 2 x One, Sub

We use room 2 far more than room 1. We’ve already moved the sub, which was originally in room 1.  But now I’m wondering whether also to swap the surrounds. Swapping the sound bars themselves would be more hassle so I’m disinclined to do that.

I care mostly about music playback, and have the surrounds in ‘full’ mode, but improvements to TV sound would also be nice.

On the face of it, “three” is better than “one”, right? So I’d assume swapping the surrounds would improve room 2.  But… given there’s already a sub in room 2, does that render some of the Play:3’s advantages redundant?  Similarly, the Play:3 is older tech than the One. Does that matter?  Finally, I don’t want to completely ruin room 1 so if downgrading the surrounds there will make things noticeably worse, especially with no sub to compensate then that would militate against.  Oh.. and the rooms are 150 miles apart so “just try it” would be easier said than done… I only want to go to the logistical hassle if it’s likely to have been worth it!

Hence my question: how much difference would I likely notice by swapping the surrounds for the systems described above?
