MrTennis - Unfortunately, the term 'warm' to describe playback is inconsitent among audiophiles. To you, clearly it means "loss of detail in the treble region."
To BigTee, 'warm' means midrange body, and may be irrelevent to the upper register.
To me, it may mean something else.
I think a point of confusion is that you can have two different playbacks, both measuring ruler flat, and one can sound "warmer" than the other. This is because there are many other attributes of audio that play a role in what we hear other than the freq. response.
Take 2 speaker drivers, one made out of aluminum, the other paper, and the third plastic composite. They all measure ruler flat, but they will all have different sonic characters, perceived "warmth" being one of them.
