Best speakers under $500? Fire away!

With my current Klipsch, I am only approaching max output with the amp at very, very high listening levels.  Perhaps the ELAC's are not a good match as many are saying here.  The MA's sound like a better match.  

ELAC's are 6 ohm.87db
Wharf 10.1 are 6 ohm 85db
MA Bronze 1 are 8 ohm 87db

I listen to music at "normal" listening levels.  

you not only can't tell by the numbers, the published numbers are not always accurate or measured the same way...

Have you considered focal 705?  8ohms / 89db 

I can give a personal example the McIntosh integrated amp MA6700 has a power output of 200W ,my McIntosh MC152 power amp has only 150W theoretically my power amp should be less powerful than the MA6700 but it’s not !
I heard them both my amp is much powerful,transparent and detailed than the MA6700 ,That’s show you the published numbers are not always accurate or measured the same way...
