When it comes to what you are installing in your HOME on a new build, I would stay away from anything that is current device dependent. In other words, who knows what we will be using in 5 years or next year to control our music, lol..
For whole house audio, I like a simple 2 channel amp, and a selector box with separate volume controls..
So its really simple, you get a 4ohm stable 2 channel amp

then you get a selector box

then a volume control for each room

speakers (I like yamaha for decent sound and affordable), cable (mono price).
NOW for a source you get an AVR that can handle zone 2, most decent units, and if you want to control it with your ipad get an avr that does that...
You will have a future proof system, when your avr is our of date, thats all you have to change..
NOW I listed the cheaper stuff, the sky is the limit, my brother is using a tcc selector that allows you to put 2 amps to it, so he is using a pair of emotiva xpa 5 (4 channels and then 1 channel for his rec room built in sub woofer..) He has a volume control knob in each room...
So the issue with this type of system is 1 source, my brother has 1 inside and one outside with an avr that is 3 zone supporting. BUT what I have noticed is, we use 1 source at a time, I have a large house (4500 sq ft) and we use one source, when my wife is cleaning and has the tv on she walks around with the zones playing what the tv is saying, or music. When the kids just want some music outside, its normally what ever they put on, and its on inside too, if you dont want to hear music inside, then you just turn the volume knob off for that zone...
Simple and cost effective, as well as easy to install program etc... I have 8 zones, 1 source. 16 speakers running off of a 200w amp, and they are loud...
I wouldnt go crazy with it, I would just put a 2.2 system in every room, lol...
