The current WB Square 2's are a fantastic speaker - great insight into the music, you can hear everything that's going on. It's downfall is that the rather lean, forward sound doesn't do bad recordings any favours. Because of this, they're not the best all rounders at this sort of price point, which that accolade would go to the ATC SCM40's, which tend to be able to reproduce anything thrown at them, given a good enough system to drive them. The Spendors will be better all rounders, mainly suited to real instruments, but they also deal with electronic type music well too, like Hybrid and BT for example. Your choice would depend on the amplifier being used (you'll need a better amp for the WB's than the Spendors), but overall, many will probably prefer the 'nicer' presentation of the A6's.
