I have auditioned a pair of Revel Salon's directly with Aerial 20T's at my home side by side.
The Revel's from the very top octave all the way down the the lowest octave are superior. Especially their midrange transducer. Revel's imaging is rock solid and never wanders and its due to the fact that the crossover boards,components and drivers themselves are of a much higher grade than the Aerials. The bass on the Salon's is also untouched by the 802's or the 20T's. Each bass cabinet of the Salon consists of 3 8" drivers and a single 6.5" vs. just a pair of drivers for the 20T's or 802's. The Salon's are known to have the absolute best bass of any speaker at any pricepoint. Add this to the fact that you can contour the fz response at 50hz 4db to help match room placement too which is also a valuable tool. But the true heart of the Salon is its 4" titanium midrange driver and anodized 1.1" custom Scanspeak tweeter. Both integrate seamlessly and are perfectly flat in response for the best midrange I have ever heard. Alot of people compare Salon's with the best Ribbon/planer speakers made. Aerial's arent even in the same class. Even the cabinet and finish of the Salon(or Studio)is a step up from B&W and Aerial. The integration of the grills,automotive quality finish, the hardened anodized hex nuts, the port,the compressed sandwich style side panels(which play a huge key to why there is almost no resonation from the cabinet)etc all add to the Revel's classy appearance.
The 20T's are nice, but in every regard they are a step down from Revel's. B&W 800's would be a better comparison against a Revel Salon or Studio speaker.
