Good point, the early ones didn’t come with the Dynamik, there will be more out there with it than without it though. The Dynamik brought an extra level of refinement and improved current delivery over pre-Dynamik models. The improved current delivery made it better at controlling difficult loads.Agree with above, very different although both do the Linn 'tune' thing - i.e. easily make sense of melodies and follow what's going on.
Don't see many of the newer ones for sale - presume they didn't sell high quantities. Don't recall if the earliest ones came with factory fitted Dynamik PSU so worth double checking if you do find one.
