Zavato, I agree with your assessment of loud. And I DO enjoy lots of music approaching those levels, or just below; that's where a good system can reproduce the energy of a live performance. I ensure that I'm not disturbing anyone, and carefully limit my exposure to such levels (I'm not a high-hours daily listener). And music rapidly becomes very unappealing as you push beyond this level.
My problem with systems that do low levels well is that they're usually the result of a modified response curve that complements our own hearing's non-flat response curve at those levels -- the Fletcher-Munson curves are oft-referenced here (though they may not be very accurate). That's not a route that I prefer; I like gear that yields fantastic realism at loud levels and is completely non-fatiguing -- so in most cases bright sounding gear doesn't gel with me.
