Thanks to everyone who has responded. I tried to find a supernova in my town (because they just look so cool...) but failed.
In the end, I ordered the cambridge (becaue it was a mailorder) and bought the ayre on this site even though it didnt have the input because i figured that if I liked it enough i would just keep my dac1. I will let everyone know what I think about the ayre when it gets here next week. But as far as the cambridge goes, I really like it so far. both as as player and as a dac for my sonos. Need to play with cables and make sure that is not the reason but so far I like it better than my benchmark as a DAC. More in the next week.
