I humbly defer to Dave & Grant's opinions, speaking as people who
already have SpeakJets hooked up to their PSIMs, that the additional
I/O would be more useful.
One thing to consider is the additional front panel space this might
take up if you build up these additional inputs with the full
complement of pots/jacks....
