I've never been a big fan of the highly revered LS3/5A. I've crossed paths enough with the Beeb's mini-monitor design enough times, the last being a Rogers example a few years ago. I won't deny that the design has its virtues, chief among them -- when given the right acoustic environment and partnering ancillaries -- a stunningly gorgeous midband, but there were also enough association headaches. It was a real mule to drive, the treble was rolled-off (though very gently and linearly), and there was, well, simply no real bass to speak of.
Still, like I said, the professional application design had its moments, as prompted by the many who ended up toting one home (and who still use it; many LS3/5A users are die-hards), and must have been revelatory as a close-in, nearfield monitor when first introduced, but time, standards and expectations have moved on since then.
