Yep, and the fun begins! I don't have any idea what your system setup is, but I can tell you that all of us have recordings that show us things about our system that are interesting. We might be able to play 10 recordings in a row and that tenth recording just goes completely dead, dull, bright, squeezed or whatever. We at first suspect the recording or pressing (and it can happen) but there is more times than not that it is actually in our system's mechanics.
When I start tuning someone's system the first thing I ask is "where do you have dampening and shielding". Most people have over dampened their system thinking they are isolating it, resulting in squeezing some part of the signal. Once you start controlling the signal and not so much dampen it your going to find all kinds of music and stage.
