Zaikes is correct. I could be assuming the worst, and as we all know, assuming is bad. I use an Anthem Amp2, and do find it to sound more open without a LC. I think a listening test is in order. What I do is keep my favorite cds in and listen as much as possible for a week, make my change, then listen again for a week. I can usually pick up on changes right away, but find it takes time to interpret weather or not the changes are for the better or worse. I recently purchased a Monster AVS2000 and find things to be sharper when running through it. But hey, that's just my gear!!!
Good luck Jetson. Let us know what you find.
