I can say is that they are a new standard in its price range. Revelation 2 impressed me a lot. The Rev.3 has more bass extension, but it seems that the Rev.2 is more accurate on midrange. The sound from midrange to low bass is more tight. Box cabinet of Rev.2 seems to be more compact.
Highs are sweet and very nice extended.
The soundstage is big with good focus, they work like a minimonitor. These speaker always make music.
