i have ownend two different versions of magnepans and listened to many others at shows . i have heard the analysis speakers at shows and also at the importer's house. i used tubes on the maggies.
i have many ribbons at shows and have found the treble sounded elevated.
i have speakers with ribbon tweeters and again, i found them peaky.
i will admit that it is my ears and my opinion..
others may differ.
i realize in this hobby there is much contention about the sound of stereo systems, so i suspect there will be disagreement with my premise.
