Chrissain, I surmise that a significant reason for the excellent performance of the Salons and Studios is because of the beryllium tweeter. It's an expensive component and hard to manufacaturer. But ... it's performance attributes are stellar. There's not many companies that manufacture beryllium tweets. Other than Revel, there's Magico, Focal, Usher and Paradigm.
I happend to own the Paradigm Signature 8s (v3). Another performer on steroids that is reasonably priced.
I've read the bench test specs on many other high-priced so-called darling speakers. Frankly ... I've been underwhelmed. I appreciate that there's no substituting for a live audition, but as many have lamented, not many B&M stores around any more. So we're left to trial and error.
Anyway, the Revel Studio 2 is on my short list to try (??) and listen to one day. In the meantime, I suggest that folks with good front ends and source input materials give a serious listen to the Paradigm S8s (v3).
A word of warning. I agree with the comment above -- this type of speaker is not forgiving of bad source material and they should be driven by a very high quality, high current, high power output SS amp. I kinda lucked out with my ARC tube Ref 150. But that's a story for a diffferent day. If interested, check my posts. It ultimately came down to power, low output voltage, and a very robust power supply.
