There is first and foremost a variety of musk types. Apparrently pure musk is very rarely used these days in fragrances, so most musk notes are synthetic approximations. If, for example, we are to believe that the SMN Musk fragrances have not changed since their inception during the Middle Ages, then Musk is generally a bit soapy, a bit bitter, and slightly powdery, but almost always with that sweet edge that most of the musk scents on the market seem to have. Kiehls is somewhat of an exception - not very sweet, and slightly medicinal.
So De Varens Musc is a good interpretation, but the name - "Absolute" - is not really fitting in my opinion.
