My strategy will be to play it safe and go with a high current SS amp that doubles output into 4 and eve 2 ohms as much as possible and has a higher input impedance, along the lines of those I mention above. That will optimize electronic interfaces both in from pre-amp and out to speakers.
From there, whatever amp used will be in an optimal position to synergize with pre-amp and speakers and deliver its best performance as a result, whatever that may be, I would say.
