If one browses through the various other forums one thing to note is that the thing that seems to get most attention, (and gives rise to most "after purchase" disappointment), is not the sound but whether there are any "gotchas". Such things as whether it can upscale HDMI, whether room EQ can be applied to bit stream inputs, flexibility of input assignabilty (not just for Sky btw) etc.
Admittedly these are not major issues for most people but they might be if one wants to upscale SD from a Sky HD box, or to connect a Wii with component video and analogue audio. Or perhaps one might find that room EQ settings give a preferable sound and would like to use these irrespective of source. There are work arounds for all of these but it doesn't stop consumers getting hacked off.
My view is that at the £700 price point no product should have limitations that can only be found in the small print, irrespective of perceived importance. Yet out of the Denon, Yamaha, (and Marantz) there appears to be only one that provides the flexibility that it is reasonable to expect.
Sadly, these issues do not get much weight in reviews and are often only found after buying and living with the item.
