Plus, should you decide you want some coloring, "neutral" (as close as one can get to it) is a better starting point. My neutral setup can have its bass boosted correctly more easily than a bass-boosted system can have its bass-boost removed.
Extended use of a neutral setup is a requisite.
If somebody consistently turns up the bass when listening to Bose or Beats or something that's are known for being bass-heavy, do you really think they'd need a neutral setup to know that they like bass?
