Best speakers for Sonos ZP120

I have aSonos ZP120 that I have not yet connected to any speakers. My main systems are in the lounge, kitchen and dining room but I may as well set this up as well as I have the unit sitting there. It will be in a medium sized office. I was thinking of a pair of speakers on stands. Any recommendations both for speakers and stands? I suppose in terms of budget I was thinking £500-£600 all in. Thank you. Mark
