Atmasphere, in each system that I used for this test the players were different; one is my own which is the Shanling CD-100, another is an old Theta, and the third source is our Apple TV playing Apple lossless files. The results are the same in all cases using multiple CDs when the offending frequencies come up. For example, I can't listen to anything Celine Dione sings except at VERY low volume. Mostly, though, because much of my listening is to solo guitar, there are only a few passages that bother me so, yes, most most of what I listen to is pleasing and I generally enjoy my system very much.
Labtec, I got out the old test CD and tried listening to pink noise but didn't quit get the part about a comparison. The test disk presents pink noise starting at the left speaker, then right, then simultaneously, both in and out of phase. The thing I didn't expect nor understand is that the out of phase sound was almost exclusively from the right speaker. I'm sure I'm missing something here.
