Part of the problem is the Klipsch speakers are super efficient, so comparing their performance to the B&W straight across is like tying two arms and a leg behind your amplifier's back. Not trying to defend the B&W 600's, but this is not an apples to apples comparison.
Question: do you really want floor standing speakers? If so, quality floor standers for around $1000+- I would look at these:
Infinity Beta 50
Monitor Audio Silver RS6
Monitor Audio Bronze BR5
Axiom Audio M60 v2
Focal Chorus 716V
Paradigm Monitor 7 (Great Deal)
B&W 684 (yes, really)
Klipsch Reference Series RF52 (why not?)
Aperion Audio Intimus 5T
Polk Audio RTI A5
