KEF LS50... The ultimate anal-ytical speaker for living rooms?

I am looking for a VERY revealing with razor-sharp imaging type of bookshelf,  but not the cost of TOTAL loss of musicality.... In other words, not necessarily full range, but at least balanced - not something that starts to roll-off at 200hz... They would be listened to mid-field, 6-7ft away in a somewhat open space.  Could it be the ls50, or is there anything else around their price-point? Thx for suggestions...
