I agree with Lugnut. Every recording is different, and no single recording is absolutely perfect. Never judge your system based on one recording. Try to listen to as many similar albums as possible and you will see how your system handles the brass on a variety of recordings. That's the only way to get an accurate reading of how your system handles that particular element of a recording.
Different recordings were done with different players, in different rooms, by different engineers, using different equipment and different media...mixed and mastered by different engineers using different equipment and different media...pressed in different plants by different people using different equipment. Like audiophiles...all engineers have their own ideas of what music should sound like. Their recordings will reflect their individual taste and skill (or lack thereof).
