Every component has a sweet spot so to speak. This is where "synergy" comes into play. It's more than just the ideal operating point of a single component rather when all the components in a given system work together at their optimal levels to produce the best sound a system has to offer.
Lets say you have a perfect mate (okay, great match) between an amplifier and speakers. If the preamp is not a good fit to the amplifier (or amplifier speaker combination), you may blame the amp for the system's downfalls. Volume may get too loud prematurely or you may have to crank the volume to get the speakers to play at normal levels.
With an integrated amplifier that has been designed properly, this should not be an issue if matted with the proper speakers.
