Thiel CS3.6 and PrimaLuna

I have a pair of Thiel CS3.6 speakers and a Primaluna Dialogue Premium HP Amplifier going thru a Mytek Brooklyn DAC/Pre.  The sound is really good, but I know the Thiel's can do much better.  I'm curious to see if folks would recommend going to a different amp (high current SS) or moving to a different set of speakers.  Either option is viable, just curious to see what folks think.
