I know this is a bit of a late reply but...I chose the Graham Chartwell LS3/5 after comparing to the same company's LS3/5a and the Falcons in a lengthy at home demo. I love these speakers. I find them a bit bigger sounding, less dry than the falcons but more accurate than the LS3/5a. Bigger sounding than both really, with more accuracy and space. A bit less velvet on the midrange maybe. Since I've listened to the G/CW LS3/5a often at Gig Harbor Audio (disclosure I work there) and I'd love to run the comparison again...both are really good. Rogers put out their LS3/5a SE, more expensive, but may be my over all favorite. Haven't had them at home.
Anyway the LS3/5s aren't going anywhere. Amazing speakers.
