Airport Express is made to do what you want to do. It will require an
amp - look in ebay or cpc for a cheapo one, and a nearby main socket.
I'm doing what you are doing in my kitchen. The airport output is a
3.5mm minijack, but thats easy enough to connect to your amp then your
speakers. £80 quid or so for the Airport express, cheaper on
ebay..However, there is a possibility of an update to the Airport range
in January (mac expo) so you might want to wait..
