I understand that we all have different opinions when it comes to terms like warmth, transparency, boxy etc... However, most people tend to view wamrth as a kind of coloring. This is what I was referring to in my comment. Personally I love the Grace stuff for certain things. They are very clear, and they definately get out of your way, almost to a fault. A sort of side effect to that though can often be perceived as a "sterile" quality. Every pre and mic has its place. In general though, it seems that 99% of the people I know equate "warmth" with something that would be "colored".
