Bifwynne: Apart from the normal evolutionary improvements which a manufacturer engages in over the course of normal production, the Kleos has not been through a major revision.
If you are referring to the wording on our website - the "Level 2" is in relation to the Delos, which was the first cartridge to get the "New Angle" suspension technology.
If or when I make a revision to the Kleos or Delos that is significant enough to talk about, I will do my best to keep it retrofittable to the existing version - so that present owners can upgrade for the price of a rebuild.
Sorry if I disappointed you (smile).
