Denon 887/2307 users..Volume levels?

[Amon37]

I know this is a very hard question to answer given everyones different room size and speaker types but can I get an idea of volume levels when watch BD's with PCM.

I sometimes have to turn the volume up to -20 to -15 to get it loud and that seems awfully high. When I watch TV(Dish Network) it's at -40 to -30 on normal channels and -30 to -20 on HD channel with DD or Dolby Pro Logic.
