JohnDuncan:You're not gonna find one (yet, if ever). Closest you will get is something with iPod integration.On the plus side, an Airport Express won't sound half bad on its own.
Ummmm, Onkyo 725DAB. In my opinion sounds better than the Denon (had the DM37 as well), has optical input, and none of the annoying humming or hissing issues that seem to affect the Denons.
Don't think many places sell it now, but you can get it for under £200 new if you find it.
