Actually, with the caveat that they are limited to +20 dB transients, some of the best produced music today are movie soundtracks.

Yes, good classical is pretty awesome, but organ symphonies will test the mettle of all but extreme sound systems and find them wanting, especially if you want to go ~ 'live'.

Accuracy/smooth are 'floating targets' since folks don't all hear exactly alike, have different frames of reference, etc., and if you fall back on measured 'perfection' to level the playing field, most folks find them too 'sterile' sounding. For instance, all expo horns are 'colored' (distorted), so anything but accurate and the 511/811 conical/expo CD horns are much more so no matter how much you tweak them, yet many folks consider them 'accurate/smooth' enough without any tweaks. Then there's the woofer and XO to consider..........

So the good news is that you can technically improve what you have and the bad news is that you can't make them 'right' and might not like them once you're done. Still, as you know you're starting at a high enough level that few do much tweaking, so major leaps will require mass quantities of $$ and ultimately, space.

Note that unless you have room to toe them in, a horn super tweeter will be required to get enough off axis HF power response. This, or make horizontally slanted front baffles like the late NHT 3.3 tower system: http://www.stereophile.com/loudspeakerreviews/1293nht/
