First heard the AC Leisure2 SE in its original form at a freind's home, and I was really impressed with the build quality and performance. Recently ordered a pair from KAVD, which is modified in many areas. The result is much better and simply fantastic. It has the best highs, clear smooth mids, and an incredible bass for this size of a monitor. I can clearly hear bass E at a tightly controled fashion, which indicates a bass extention close to 40Hz, very rare in this league.
