So, not sure about ya'all, but color me impressed.
So far, it has played all the shiny disks I have thrown at it with great effect. This as well as accommodating the optical out of my squeezebox for Internet radio and the HDMI output of my appleTV for streaming audio from my computers and IOS devices. Again, all to great effect. I personally like the sound quite a bit, even at this early stage of getting aquainted.
With the right amp/speaker combo, this unit can certainly act as both source and pre-amp. Sort of like a nice all-in-one combo. A least, that is how I am currently employing it. Source => Amp => Speaker. Looking forward to using it to access a NAS as a dedicated music server. If that works as I would hope, then I think I will be quite happy with the purchase, at least for the price/value ratio, which, seems quite high at the moment.
Note, I have yet to try out any of the video or surround capabilities. Also have not plugged any headphones into it either.
