Ron, if you don't mind, I'd like to respond to this also.
In my ideal world, I'd like to see something on a boat that is like Sonos. I don't know if you're familiar with that home audio brand, but I'll expand anyway. So, we've got some pitfalls with BT systems, right? Stray 30' away from your boat with your phone, signal drops. Have phone alerts on, and playing music loud? Yeah when you get that text alert or the phone rings, it really wakes folks up. Want to play different playlists in different zones? Party in the cockpit, little nap time in the forward berth? Nope, can't do that.
A Sonos or Sonos-type of solution would be perfect for this. What it would require though, is some sort of infrastructure WiFi arrangement. Not terribly difficult though, in today's world. High gain WiFi antenna, a router or two, done. Easy. I'm actually adding that equipment to my 380 this weekend.
The ability to aggregate all of your music streaming services and sources into one easy to use package that's *not* BT dependent is really nice. Add the ability to completely control every zone independently is the icing on the cake. Here's a sample screenshot if you're not familiar with the system

And for what it's worth, I would pay a premium for this type of system over all others. It's that good.
