The answer to the first question may be my output source, but I wanted to check and see if there was any set-up solution. When I'm streaming music from iTunes through an Airport Express, the vocals sound like they're coming from a valley or out of a can. I'm not sure if that is the correct term, but the rest of the sound is amazing (at least to my ears). I recently moved, so all of my CD's are still packed and I can't compare an ACC compressed version against a CD version. Any thoughts? Also, I'm using a Pioneer universal player. I originally used a optical audio connection, but I couldn't play SACD. So I connected it with mulit-channel analog cables. This allowed for SACD, but when I tried to watch a movie I was able to hear all of the other sounds of the movie, but the dialogue was absent. The previews included dialogue, but when it went to the actual movie the dialogue was completely missing. I reconnected the optical cable and they returned. Any thoughts? Thanks in advance Brandon
