Revel’s Sound Signature

I use Revels in one system and Monitor Audio in another.  There is a wide difference between the systems and a wide price gap between the speakers.  However, I chose and enjoy both because they appeal to me in the same ways.  I don't know what models you are considering but I think the MAs are much, much closer to the Revels than either Paradigm or NHT.

To me the Revel Ultima line (Salon / Studio) sound is accurate but dry.  Far from Monitor or Paradigm and as Eric mentioned above similar to current Wilson designs.  Like with the Wilson's, bring lots of power with good current capability to get them going.

I think the persona series is akin to the Ultimas. There is a grandiosity to Salons, though, that is hard to replicate. I think are similarities to JBL Synthesis line as well, in that they both dry, big and dynamic.    

Nowadays, there are few and far between good audio stores to demo new speakers.

I wonder that phenomenal myself.  I've read a study that show younger generations don't really care for "cars" as much and for them "cars" are just something to get from point A to point B.  I wonder if it has to do with the Internet.  Younger people are probably using the Internet as a mean for "escape" so music reproduction (such as a hi-fi system) is not that important to them.

Kef has similar design goals with wide flat response and both brands need gobs of power while neither will bowl you over with their bass
