Guys, RM's problems are exactly the same as I've experienced. I think when he refers to lack of bass, he's hearing a lack of timbral fullness like I am. In other words when you hear a piano recording, its as if the piano is set up at the beach instead of the concert hall where all the fullness and richness are gone and you just hear the surface tinkling of the keys.

I HAVE tried bass to full and engaging the sub. Even though I have a very musical sub, it doesn't make up for the severe lack of fullness in the sound but does help in some cases.

I also have full range speakers capable of tight and deep bass, so having to engage the sub points to problems elsewhere. When I had my cheapo Rotel pre/pro, the sound was very full and I never had the sub engaged.

Its just so weird that DD and DTS sound so full and "right" and 2 channel sounds so thin and "wrong". Maybe it is a defect we're both experiencing since I don't see how anyone could be satisfied with the 2 channel sound as I'm hearing it. Unless either they are used to poor quality components, or if they only listen to music in DLPII or NEO6 (which does give a fuller sound, but mucks up the presentation).

Scott - if you're listening - could it be that we both have defective units?
