The fact of the matter is that the bulk of audiophiles' systems are not that good. Contemporary music sounds bad on these systems because they simply cannot handle it, while superior systems can. It's foolish to blame the genre of music when the system is poor. If you're running a $5-10K rig, then do not expect such music to sound great. Conversely, anyone can delude themselves into thinking their system is all that when it sounds good playing simpler, less challenging music. The fact is that if the modern music sounds poor on your system, then it's not that great of a system, and/or you didn't set it up well.
If this were true then why at audio shows do I not here a wide variety of music, usually the same Audiophile recordings. I know your going to say it's the room.
