I also dislike the touch sensitive power button, which is hard to find by touch.

Feature set is great, but power seems barely adequate, I don't believe it is 50 watts/channel, an older 20 watt amp pushed the same speakers much louder and 'fuller' and based solely on recollection, nowhere near as powerful as the original NAD.

The headphone section is bit better than anticipated, certainly better than a laptop or iDevice (which have good output sections just not great power).

I switched 2.1 speakers from very nice older Mordant Shorts to more efficient Q-Acoustics 3050's looking for better mid-power performance and I also upgraded the firmware.
