Home Theater Enclosure Problem?

I can hear the TV perfectly when it is played through the Arcam. I never miss a word. It's only on DVDs that I miss words occasionally.The digital signal is sent to the AVR 250 via a Transparent Premium TVC 2 meter digital cable. The viewing room is 20'X 30' with a 17' ceining. There is a staircase coming down into this room on one side. Sometimes it appears thar the audio is plainer when at the top of those stairs. There is thick carpet on the floors and stairs with a cloth sofa and loveseat. There is nothing between the center channel and the listening position.

In that case it may be normal. Movies are often mixed so that they can be played at louder volume levels than a radio or TV program. They want those sound effects to really envelope you. Simply turn up the volume. What concerned me was you menioned muddiness in the sound....that is not normal.

Pride and Prejudice is an example of a movie where the vocals were mixed too low, IMHO.

I have been looking into purchasing some brass footers for my components. Has anyone used the Mapleshade Ultimate Triplepoints? Thank you.
