The initiation (Wifi, manual input of the WPA key in my case) and well thought ergonomics for using Internet radio as well. The remote is big (too)
The Denon is relatively distant from the box (fifteen meters with a load-bearing wall between), but no Wifi reception side concern. DLNA works from my player Media (Windows 8) without problems, as well as from the outer disk of the box numéricable (DLNA server that makes office): Result 150 permanently available to CD. Support VBR WMA format and also the WMA lossless (I use for classical music)
Some more advanced functions (play podcasts) are not ultra practices (no way to bookmark) and are more of the order of gadget than anything else ... The other downside is that the product is definitely end of life, due to an older generation iPhone connector (... thank you Apple). It is therefore possible to find a much more reasonable price than the launch price.
The Android app is not super compelling (used on a Iconia tablet). Some crashes (but may be related to the tablet, I have other apps presenting the same symptoms)
A USB port on the back would have been welcome to put an indwelling storage while preserving the design of the whole. Bluetooth support too.
