oblgny - thanks for the comparison, if you wouldn't mind, what kind of differences do you hear between the 2.3s and 2.4s? Like you and prof have mentioned, I love the way these speakers sound from an adjacent room. My kitchen/dining room is adjacent to the listening room, through a 3 foot door opening near the front right speaker, and I greatly enjoy listening from the next room, lots of "wow" moments there, and like some live music venues, you get pulled into the main room bc it sounds so real from next door.
