I'd like to add that, at least on my system, it doesn't seem to be a bad thing at all. My sides and rears are placed at 100 and 140 degrees respectively, so when I listen to 5.1 mixes in DTS format the rear sounds seem to come from around 120 degrees, which I actually prefer to the 100 degrees option (which feels too close to my ears sometimes). I have compared the LPCM and DTS options for the same mixes many times, and I tend to prefer the latter precisely because of that. I guess this will depend on how your system is set up. It works for mine.
