Hi guys. Considering picking up some m's or mm's. First, is there a difference between an m and an mm? 2nd is the difference between an mm and the mx only its finish? Am considering these speakers with the manley stingray in triode, what do you think? currently driving N805's. Should i switch to pepsi? I like the 805's in varying degrees but have become very curious about the merlins due to the overwhelming reviews and enthusiasm seen from reviewers and owners. I am reluctant to switch because i dont want to do all the work to switch only to be disappointed. I'm questioning wether my amp/speaker have any synergy. I dont know of anyone else who has this combo and I dont have that much speaker listening experience. I know the 805's with the right room and components are very good but still not convinced that I have synergy between them and the amp I currently have. Thoughts?
