A musical speaker?? A totally subjective, and quite frankly, useless description. Unfortunately, it is used by audiophile all the time. In my experience, musical basically mean a coloration of some sort which for some reason one may fancy . A speaker should be as true to the source as possible. That does not mean analytical or austere, which are also forums of coloration. To my ears the Rockport are much less true to the source, and therefore more colored then the Magico. You may fancy that but I would not call that musical. Listen to a cello recording, and immediately after to a soprano. It takes a second to hear how significant the loudspeaker coloration on the sound is. To my ears, the Rockport sound is more evident than the Magico one.
Different strokes for different folks. It's funny how we all perceive sound differently. To me, the Magico sound is anything but "true to the source" if your reference is live unamplified sound. To me the Magico sound lacks any of the organic natural texture of instrumental and vocal timbres. It sounds clean and highly resolved for sure but lacks texture and body and sounds almost austere and clinical to me. But this just goes to show the OP that opinions are just that opinions and one has to go and listen with their own ears and see what is pleasing to you.
