FrankHarveyHiFi:It depends what you mean by the best. If you mean accurate, not everyone likes accuracy. Many people would be happy with a smooth, unoffensive midrange, whereas others want to be slapped in the face by it.
And I guess that depends on what sort of music you listen to? I like a wide cross section but a lot of it is electronic based (80's music and stuff like Groove Armada's current album). When listening to that I want the midrange and upper bass synth sounds to be punching me in the chest, physically, which also means reasonable volume levels.
