Totaly has a little disappointed on the hard drive me to navigate. Even the small screen is a hindrance when navigating. While efforts are being recognized ID3 tags very quickly, but you can only by genres, albums and artists sort. You can not sort by title name and an evaluation possibility of songs missing. The search function is not particularly Ganu.
Positive on the system is the Internet Radio, which is activated for a firmware update and it works well. Also, the sound, the volume and the design can be very convincing.
Conclusion: If you want to use the hard drive as the main medium will be a little disappointed, but otherwise the plant is quite recommendable.
Addendum: Warning! For me, the delivery was not as advertised but the WAC3500D the WAC3500 (without D). What makes that I do not yet know, but investigations are recommended
