The problem is that I have already done this (set bandwidth to real experienced levels) and it sounds bad.
I get better results with the way its set right now, however it still has periods where it sounds bad. I'm considering setting it to 90% of real experienced levels to see if that helps. I'd like it to be as good as in my office, but I also have alot more bandwidth. But the shaping seems to work MUCH better when it has more bandwidth to deal with.
