the "Superlink" does nothing to a 282 when powered to a hicapdr.
I would not expect the Superlink to make any difference to a (2)82 plus Hicap: nor to a (2)82 with two Hicaps. In neither configuration is the Superlink increasing the number of secondary rails available to the (2)82, as compared with the standard 1xHC or 2xHC configurations.
And a SC will provide no more rails than 2xHC to a “standard” (2)82 - I.e. four. It is a matter of debate whether 1xSC is “significantly better” than 1xHC or even 2xHC. (Personally, I felt that 1xHC->2xHC or 1xHC->1xSC gave a significant improvement with my 82, but that 2xHC->1xSC was marginal (and yes, I did spend a happy Sunday afternoon trying all configurations - however I do accept that my judgement towards the latter stages might have been impaired by several glasses of Pinot Grigio. Other opinions are, of course, available.)
(Note: for the current discussion, we are not considering the NAPSC, because it is needed whatever configuration is implemented.)
Where the Superlink “should in theory” score is that it will enable the use of more rails to the (2)82 than standard SC or 2xHC configurations.
But it will need the acquisition of a Supercap - hence
@Finkfan saying that he is now on the lookout for one.
As an aside, there could then be an interesting comparison between a non-DR SC into a Superlinked (2)82 versus a SCDR into a standard (2)82
