Why should i be a fan of Revel speakers?

I think Ncarv summed it up pretty well. The Concertos sound great, they are non fatiguing, you can listen to them for hours on end. They are smooth and more forgiving of mediocre recordings.

The Revels have incredible transient response, they are small speakers that are fast and dynamic. They have surprisingly good bass and are very well balanced across the spectrum with great extension. They excel with great recordings , they reveal the warts on bad recordings. I can’t comment on the M22s because it’s been a long time since I’ve heard them. So a little more than 2 years and I still love the 106, which says a lot because I’ve owned a number of speakers over the past 30+ years. I replaced a pair of PSB M2 Platinum monitors with these and they are one of the few speakers I regret selling, they were a great speaker too.

I asked earlier differences between m22 and 106....if any1 knows
Is M106 the higher line? 
Thanks

I wouldn't say they are the "masters" of anything,  I wouldn't expect them to be for their price ....but they are damn good for the money . 

The Aerial 5t is on my short list , that speaker is almost twice the money.  

IMO Revel offers superior quality from the cabinets to the awesome sound . I have Performa 208's and Salon 2's and can't imagine better products at their price points. If these don't light your fire in a demo then something's not set up correctly. I have zero doubt that the smaller speakers in the Performa line would be leaders in their price class.
