Hi all, I recently bought myself a couple of play 1's to get me started. The plan is to expand over time. I'm happy to listen to streamed music these days but the wife is insisting that we must have a CD player as we already own hundrends of cd's. I'd like to get a sonos set up in the lounge and the choice comes down to 1x play 5 or a pair of play 1's. I know that the play 5 has a line in (to connect existing CD player) but is there any advantage of using a connect over the line in on the play 5? If not I'll just listen to the play 5 and compare with stereo play 1's. Also if I use the line in on a play 5 is there a time delay between the music in different rooms?
