There are good speakers. There are great speakers. However, few speakers are able to surpass mere greatness and cement themselves as the stuff of legend. Unless you're talking about the Magnepan MG 3.6 of course, which I am, and yes, they're every bit as good the legend would have you believe.
From a sound perspective the MG 3.6s are phenomenal speakers and sound more like live music than probably any speaker out there today. They are incredibly natural and smooth from the midrange on up to the highest frequencies and while they're not exactly barnburners in the bass department, what is there is incredibly composed, textural and musical. Those of you with a taste for heavy metal or action movie soundtracks should consider a high quality subwoofer to augment the MG 3.6's low end. System matching is very important with the MG 3.6s, probably more so than with traditional box speakers, for they can be ruthlessly revealing and are not what I would call ideal for all types and genres of music.
