Haven't worked with it for a while, but Epson Enhanced Matte (did the name change recently?) had a very good D-max using the standard Epson profiles.
However, there's more to the story... It also did not have particularly good separation of tones in dark areas somewhat above D-max, the ability to achieve a relatively deep black was not without side effects. There were other matte papers that had an overall better looking tonal quality in those darkish areas, in spite of a less-than-solid D-max. You have to look at some of your images printed on various papers to know what you really want.
