I just pulled the trigger and purchased a new 806. I was very excited to get it home and put it in my new entertainment center (it was an expensive weekend) and when I slid it into the receiver spot I thought to myself "there is not a lot of clearance above it, damn this thing it tall"... anyway, this brings me to my question. How much ventalation space do I need above my 806? I have read alot about heat problems with the x05 series and alot speculation about the x06 line, but have not seen much feedback from actual x06 owners. It the heat issue still a problem, and is it actually a 'problem'. Also, are you runing an external fan solution.
