Debating about Alpine iXA-W407

[DIGItonium]

Does anyone have experience with the Alpine iXA-W407?

I'm thinking about ditching the Kenwood DDX-814 and get something simpler that can fill the double-din to simply play the radio and tracks from the USB stick. It's a downgrade, but also a change in priorities. I don't care about DVD playback, and I can live with a lower resolution screen as long as it is readable. However, I would like to keep the 7" screen.

What's the audio quality like? I know it has fewer tweaking options and weaker pre-out.

How about speed and ease of use? The DDX is slow, and it's embarrassing to see cheaper units access files with lightning speed. Not only is it tedious to browse through songs, it has a 255 file per folder limit.
