Multiroom speaker system

Goldie146

Does anyone have any knowledge of multiroom speaker systems - e.g. those by Sonos or Bose?

We are thinking of splashing out on at least two (to start with) speakers, and as we don't live near anywhere where we can see them demonstrated, have  to rely a great deal on online information.

As it's a large investment, I want to get it right. The last time we spent this sort of money on HiFi etc was in 1992! That's still going strong  - but only in one room of course.
