I would also add, that it is hard to know what the Engineer, producer, artist, etc. was hearing because you weren't in the playback booth hearing the play back on the studio play back equipment. So, it will sound slightly different in your system. most likely, your equipment is much better than what was in the recording/play back booth. The mixing boards may have used ICs or solid state or tube (rare). The potentiometers may be really cheap, etc. You never really know what was used in the recording booth. So you really try to do the best you can to tailor your system to play back music in a manner which pleases you and do your best to try to reproduce the music in as realistic a manner as you can.
