In addition to the Grimm, Steinway Lyndorf and Linkwitz active systems I mentioned in an earlier post, here are some other active loudspeaker systems that can compete with any passive/power amp combo for their intended application and within their price ranges:
Unity Audio Boulder (amps designed by Tim de Paravicini)
Genelec 1037
Augspurger 215 Classics w/ subs
ATC SCM110
Avant Garde Zero
Anyone can couple a power amp to a loudspeaker and there are some powered loudspeakers that are that simple, but the loudspeakers I've listed are systems. They are carefully matched to achieve maximum performance by design teams with more resources to accomplish that goal than the average audiophile has available. Apparently this is a difficult concept for audiophiles to accept.
