I realize that people like having everything on their phones, but I'd prefer in-room keypads (or touchscreens). This way, if you leave your phone downstairs, you can still listen to music while upstairs.But doesn't include any sources... Add say two Sonos Connect units and you're at $2700. Six Connect:Amp units would be $3000 - and that assumes you need exactly 6. That also gets a single-app solution for the whole system. No in-room keypads, though - if Sonos would just do a modern, small touchscreen they'd have it all. Russound and NuVo both have keypads for their zone players (Russound has an expensive, but full-featured, touchscreen, NuVo has a simple on/off/volume/source selector available).
One of the big benefits of the zone player setups is the ability to buy exactly the number of zones you need, and there's no big "cliff" of expense when you want zone #7 , for example. It also allows you to buy a few zones at a time - the Connect:Amp (unlike some of the competitors) is 4-ohm stable, so you can easily share two rooms on one zone to get started - and add more units over time as budget or usage expands...
Wouldn't there still be a "cliff" of expenses when you go to add wired speakers in the house? Or are you thinking you'd add wireless?
I'm about to have a ton of wiring done on an already-finished home, before we fill the attic with insulation and no more wiring can be done (or it'll be very difficult to do so). The house also has an old wired intercom/radio system. So I was thinking of having the electricians drop network cable to where the intercom locations are now and speaker cable in the walls for speakers (with maybe the ability to add local volume controls), then run this to where my network currently is set up. I'd have to determine the number of speakers and zones now, but then I'd be able to buy whatever I'd need in the future. And I like the ability to fill the locations where we have wired intercoms with something else.
I'm still researching the issue, though.
