Update 2:
All set up with the Mic, all went well and the menus are very pretty and easy to use. It even told me I had one of my speakers mis-connected and was out of phase.
Sonically it is brilliant, run a couple of Blu Rays and I must say impressive! The Apple Air play from my ipod works really well and I love the idea that i don't have to have my PC on. The Denon remote app is pretty poor in my opinion, it seems to do the very basics and thats it although it did find the amp no problem.
The HDMI passthrough is a great improvement (I never had this before) so only having one HDMI run to the TV is cool, plus with 2 monitor outputs is ideal to go with my projector. I need to do some more testing however as I think theirs been a couple of handshaking problems when switching my sat box on and nothing comes through to the TV.
I have a VU+ Duo sat box which has HDMI control so when I turn it on and off it puts the TV on standby etc too. The only other issue I have here is the amp always switches on to TV/Audio source which is basically using the ARC on the HDMI with the TV. As all my TV viewing comes through the VU+ Duo you have to manually switch even though the standby passthrough on the amp is set to Cable/Sat. I can get round this by selecting to hide the TV/Audio source but if I'm trying to then watch LoveFilm or Netflix I don't get any sound back to the amp.
Hopefully these will get sorted in a future firmware release, my only other wish will be for them to raise the Sub LPF to 280hz, I have Mission M-Cubes but they're directly connected to the amp for 7.1 so from what I read I have a 30hz gap in my speaker range, not that I can tell any different.
Overall I'm a happy customer at this stage and at £849 I am not going to moan!!
