Hi FrancisRoger
To be clear the Play 5 (Gen 1) only has one orientation. It is the Play 5 (Gen2) that can be configured Vertically or Horizontally.
Also know that you cannot create a stereo pair with a Play 5 (Gen 1) and Play 5 (Gen 2). Therefore in order to experience Play 5’s as a stereo pair you’d have to find another Play 5 (Gen1) or purchase two (2) Play 5’s (Gen 2).
Likewise the Play 1’s can only create a stereo pair with another Play 1 which is also discontinued. The least expensive option to enjoy true stereo separation is to purchase Two (2) Sonos One SL’s.
I know that’s not what you wanted to hear...but that’s the reality of the situation. I hope you get Sonos to the point where it is truly enjoyable for you. BTW, Stereo pairs are awesome...especially so with Play 5’s.
