I am a Vapor owner and big fan.

I have heard 3 of Vapor's offerings; my highly upgraded Breeze, the Sundog and the Aurora. Even though these are stand mounts (The Aurora is huge), the sound from all 3 was amazing. Detailed but smooth, wide and deep soundstage that surrounds you, tight crisp bass... I could ramble on but the sound is just full, rich and detailed.
I've spent a lot of time talking to Ryan about the science behind the designs and it's impressive. The aesthetics match the sound. My speakers are works of art.
While I have not yet heard the Nimbus or Joule, I would not hesitate to order based on my experience and feedback from owners. Ryan can steer you in the right direction based on your room and preferences.
