Wi-fi solution - help!

Hi All,

Just got married a couple of weeks ago and 1 of the gifts we kindly received was a Pure Evoke Flow. We also got some vouchers/cash which we are hoping to put towards a wifi solution for the house. I want to play music in the lounge, kitchen and bedroom and currently have the pure radio and a 5.1 system in the lounge all through an Onkyo 605 receiver. At present all of my music is ripped in lossless on my laptop.

I have a budget of approx £700. 

I'm assuming if I don't want the laptop on all the time I will need a NAS but I really don't know much about these (am going to have a look through the forums now). I was looking at Sonos but I assume you can't link the Pure radio in with the Sonos units?

I'd welcome any thoughts people had!

thanks,

Alex
