Look and feel are very fine. The sound is also ok. The radio sound is subjectively a bit thin. What annoyed me: For USB supports the K-521 incredible 65,534 folders, and they can not be controlled via the numeric keypad! Instead, press "Next" pause for thought, again pressing "Next", etc. The same applies to the individual tracks in the USB folders. A resume function (important for audio books), it does not really seem to pass on: USB not (after changing the source or standby is re-read the USB drive and re-start from the first track in the first folder), MP3-CD is reproduced by changing the source of the last played track of titles beginning. After "Standby" is all but forgotten. After all, these small "Resume functionality" (one may hardly call it that) of the Stiftung-Warentest testers have been sufficient to give the resume hook for MP3-CD and USB. Who does not attach increased importance to USB or audio books should not leave the device are left: - Good Full Size Remote Control - Very well-functioning sensor keys - No great cooling slots (dust) - A volume control, one can also touch (his bright lighting can be switched off) - Beautiful dimmable display - Inputs and outputs optically (PCM) - Comparatively fast USB Einlesezeiten - And a soft closing IPod / USB cover
I have the equipment returned to you because my Resume function is very important. In the absence of most of the other devices are not much better, I have decided for the Denon M38: These remembers with MP3 USB sticks at least the last played folder. Title and Folder Here can be selected simply held longer held Folder- and title keys.
