Speaker control multiroom

Hi

As part of our new extension (2 bedrooms and fmaily room) I am running speaker wire to every room with a inceiling speaker in each room.

My question is whats the best way to turn these on\off and control volume? Options I have seen include:

- plain wall switches (much like a light switch on/off only),

- specialist wall switches with volume control and

- wireless controlled amps.

The wall switch option probably starts adding a lot more cost (plates, switch) and still requires a multi speaker amp.

What have you folks used?
