Far from being offended,I think your post is very well written and informative. I don't posses the technical knowledge,but have a decent ear and 50 plus years with keyboards of all makes. I couldn't help but think of my Audya 76,and the superior sound,all around,compared to my other instruments. I think that even though there have been newer features introduced,the basic sound has diminished,even on my SD40. Newer is not always better for old boys,like myself, that don't need them.
