there was once a description of sound. American sound and British sound.
am. sound = big scale, br. sound = detailed.
americans like exaggerated sound such as boomy, more bass.
this is not true to the original music.
cooked fish with no sauce at all = you can feel the pure taste of fish.
cooked with lots of sauce = you can feel the variety of tastes
either is ok, modified sound with pre or pure sound with no pre.
once you feel pure taste with no sauce, you will remove the preamp!
