Best speakers under $500? Fire away!

Wharfedale denton, new.  Superb cabinets, laid back and smooth sound, good soundstage, at this price no problem.

Infinity Primus 363 - great small floor-standers, very efficient

Agree with paraneer. I’m sure the ELAC UB5 is a fine speaker, but not a good choice for the 3020 since it is very inefficient speaker. Take a look at it’s specifications here,

http://elac.com/product/ub5/

Since it is a 4 ohm speaker. that 85db sensitivity is actually a 2 watt rating, and it’s 1 watt rating would be 82db. That’s 13db lower than the Klipsch RB-61 which is 95db. The UB5 needs more power than the 3020. Elac recommends 40 -140 wpc and I’m thinking at least 100 to be somewhat comparable to the capabilities of the Klipsch/3020 combo.

When you are playing your system at it’s loudest, how many of the lights above the volume control blink? That can give you a good indication of how low you could go in speaker sensitivity.

GREAT info gents.  Much appreciated!
The 95db RB-61's sound great but I wanted to compare them to another contender.  The sensitivity of the ELAC's do concern me though with my vintage 3020 driving them.  
I have always been a Wharfedale fan and the Diamond 10.1's are supposed to be killer for their price.  Have no idea about the Denton's.  Will need to research.  

Any other suggestions?

tls49... going to listen at higher levels and will see how many lights illuminate.  I was at only 10 o'clock volume the other night and 4 of the lights lit up.
