Describe the Stereo Quality for Music With a Sound Bar, HiFi Set of Fives and Subwoofer - All Facing the Listener

As suggested to you in replies to your previous version of this question, you are probably best served by setting up your Fives as a stereo pair and labelling them as a “room” called Music.  Set up the soundbar as Television. Settle for 3.0 or 3.1 for your tv watching experience.  It would otherwise be odd for surround sounds meant to come from behind you to actually come from in front.
Add the Sub to the “room” you think gives you the most benefit - the Sonos app lets you reconfigure quite easily. 
 

I concur with @nik9669a.  Two stereo speakers in front of and equidistant from the listening position will always be best for music.  I wouldn’t even bother connecting them as surrounds; it wouldn’t improve music at all, and would be horrible for TV. 

Yes, I guess I’m going to have to “face the music” and opt to set up 2 separate rooms. Now the decision would be where to place the subwoofer  . . . with the Ray, probably most worthwhile or place the sub with the Hi Fi Set of Fives? Thoughts? (without my Sonos Sub, my1st gen Play:5 sounds a little “thin”)

I have these Sonos items now, all first generation. Play:5, Play:1 and the Subwoofer.  I’m going to likely buy the Sonos Five Hi Fi Set and a Ray.

Yes, the two of you are pushing me in the direction of a 2 room setup. I wonder just how horrible it would sound for the TV as the Fives as surrounds would be fairly “subtle” in volume. Guess I could try the Fives facing the listener in a “Surround 5.1 setup” (facing the listener) and see what it’s like.

If you are going to buy the kit anyway, you can try all the permutations and go with the configuration you most like. 

Surrounds are not always “subtle”.  They are used for two things; ambiance (rain, traffic noises, rushing water etc.), which can be subtle or quite loud, and directional queues, bullets whizzing past, off-screen voices, planes overhead, all of which are not subtle at all.  Having directional queues which are supposed to be located to the sides and behind you coming from the front is useless, and destroys both the front and the surround soundstage. 

But hey, I’ve seen people set up surrounds like that and think it’s awesome.  It’s really hot garbage to anyone who knows about surround sound, but there is no accounting for taste. 

Totally agree, still a little reluctant (hard to ignore the 30% discount on the HiFi Set) to pull the trigger on purchasing but will let all know if I do and how I feel about the different combinations . . . or is that permutations . . . any mathematicians out there?

Permutations.  Permutations are when the selected objects need to be in a specific placement or order.  Since you can’t use a sound bar or sub as surrounds, it’s permutations. 

I did not know about the importance of the surrounds, very interesting and revealing. This response alone may give me the info I need to make a decision.

2x rooms with Sub on either = 2 permutations 

5.1 system                             = 1 permutation
