Are we talking semantics here? There is no such thing as the "16Plus" - that is a typo. There is the EPS 16 Plus and the EPS 16 Plus in rack form. Ensoniq rack units don't have an "R" designation like some others so I don't see the need for two entries for each especially considering they are nearly identical internally. See also ASR-10 rack, EPS rack, Mirage rack.
I have owned both units and can tell you they are the same. More info here:

Ambiguous, they don't look like the same item.
