IMO, all system components should be matched as to level of performance. A $20,000 preamp will make little or no difference in the SQ of a $5000 system.
However, the speakers need to be driven by adequate amplification. That is more important than the preamp as far a SQ goes. Once that is achieved, then attention can be given to the preamp. Unlike an amp or the speakers, the preamp will determine the type of control one has over the system. Does one need tone EQ, remote control, phono input, computer input, headphone output, etc...?
