Hello Calm-One (I love that monniker!),
It's hard to answer that question in general terms because there's such a wide variety in how people have configured their Kaleidescape systems. Let me give you a single specific example that will perhaps be illustrative, and I'll use my own home as the example.
I have one very high quality music listening zone in my home (in my theater). The rest of the house uses a distributed audio system with a mix of ceiling speakers and floor-standers.
On the video side, I currently have one 4K zone (my theater), and the rest of my TVs are HD.
I have a dedicated player in my theater connected via HDMI, and a second player that connects to an analog video video distribution system (component video up to 1080i) to serve the other rooms in the house.
Upon performing this upgrade, my topology will change as follows:
- The dedicated HDMI-connected player in my theater will be replaced with a Strato player.
- My distributed player (an M500) will be ungrouped from the Premiere system and grouped with the Encore system.
- The former theater player will remain grouped with the Premiere system, and I will use it for music playback.
- I will make a new digital audio connection from that player to the theater's audio processor (probably using the coaxial output).
- That player already has a component video connection to the analog video distribution system (even though it's the theater player, I wanted other zones to be able to mirror what was happening in the theater).
So, when I want to watch a movie in the theater, I'll be watching the Strato. When I want to watch a movie elsewhere in the house, I'll be watching the distributed M500. When I want to listen to music, I have two choices. I can turn on a display and use the OSD on the former theater player, or I can just use the iPad app to control it. Either way, the audio will be going through the multichannel distributed audio amp.
Long story short, in installations where distributed audio is in use, you may only need one player grouped with the Premiere servers to use for music playback, especially if you use the iPad app for control.
