The device has many excellent features. Top sound quality, the YPAO function with measurement microphone is but in my opinion the highlight. Have tested it, carried out the measurement with any speakers in an awkward angles space. Impressive what is errreicht here after setup from any speaker configuration of sound quality. Likewise HDMI bypass in standby if the unit is not in use. My only criticisms are: 1. the remote has too many buttons, a user (eg the wife's not so busy with home theater, etc.) is overwhelmed. But can one solve on the scene function. 2. NET Radio function is very convenient, is working properly, but is awkward to use 3. The unit has an Ethernet interface, why can eg via a web interface or a tool not edit all settings (eg the favorite of Net Radio)
