Choosing the Acapella tweeter as a starting point is like wanting to build a Formula 1 race car by basing it on a set of Hot Wheels.  Oh I know it's a popular choice--but only by the frighten and fraudlent audio human waste.

I suggest the author chooses a different starting point.  First learn how to listen...because with the set of ears you currently have, you're not capable of judging good from bad or anything else for that matter.  Sure you might be happy with the final result but it won't be acceptable to anyone other than you and once you learn that, whether or not you care to admit it, it's back to Square One.
