I have been through Marantz with Heos, then Wiim Pro, Wiim Ultra, and as great as the Wiims has been, sound and app wise, the upgrade bug just wouldn’t go away.
So I saw a good deal on a Cambridge EXN100 and tried it. When I unboxed it I was a bit discouraged by the feel of the unit, it didn't feel much heavier than the Ultra, for like 5 times the price.
However, as they say, the proof was in the pudding. The sound quality is a huge improvement and the app is as easy as Wiims. Simple, straight forward with no issues. It doesn't have Amazon music, or all the eq features that Wiim has, but I can compensate for those. I could have got the lower model for less, but it was Christmas , and I am happy I did.
