I have only owned & heard one pair of Missions, and they are a wonderful sounding speaker, one of my favs, and are on my "Keeper" list.
Mine are Mission 750LE's, only 3000 pairs were made for their 20 anniversary, and were available in Rosewood veneer, and black Ash as well. Mine are done in the Rosewood veneer. Much thanks to AK member 88gibson for sending these my way!
They are currently doing bedroom system duty, with a Sansui AU/TU 7500 combo. Sound oh so sweet on jazz and classical, mostly what I chill out with in the bedroom. Haven't really tried them out on anything heavier than that, or at higher listening levels, but I suspect that they wiil hold up very well to a little bit of rock n' roll at higher volume.
Looking forward to hearing some different Mission models in the future!
