If im simply running 8 ohm speakers from an amp that is more than capable of an 8 ohm load, do I need any impedance matching anywhere? I plan to use iOS devices for my volume, grouping, source via the Sonos App. Thanks for the help before i pass the point of no return.
If you buy a multichannel amp, so that each speaker has it's own channel, there's no impedance matching needed. Since 12-channel amps are the common solution for these, you'll have plenty of channels to use.
Regarding the keypads and new construction - run cat5e/cat6 wire to a potential keypad location in each room even if you don't plan to use it. Things are changing rapidly in this area, and you might find a product next year that you'd like to have. Putting the wire in allows you choices in the future - no wire equals less choice...
You don't even have to expose the wires as blank plates - just tie them off behind the drywall and document their locations - if you want to use them in the future, just cut a hole and you're done...
