I have the 600m's paired up with the 504c and works spectacularily as well. I've used REW and mobile Denon multieq to verify. I would go( space providing) 1) 504c 2) 600c 3) 500c Sent from my SM-N950U using Tapatalk

I was in this dilemma earlier. If you go to the klipsch thread on avs, theres NOT one bad thing said about the 504. There are members that have had bboth the 600c 500c and the 504c, and do say the 504 is a much better speaker. That was enough for me and I jumped into the 504 unheard... and I love it.

I have the 600m's and 504c. They fit great together! My denon 3400 turns the 504c to -9 and the 600s to -5. So the 504 is 4db louder. But after audyssey... perfect timbre sound. Sent from my SM-N950U using Tapatalk

I have a full Energy Connoisseur system. Bought everything brand new from the Good Guys back in 2001 - 2003. I have the CC3 C5 CR3. Also I have the CC1 and CR1 that I upgraded to the 3's as I moved on. Everything still in perfect shape. They have a very laid back sound. After 18 years, it was time to move on and improve.... The Energy's have now been replaced by: Klipsch: 504C / 600M / 402S / 500SA and HSU VTF-3 MK5 subs.
