Although I've been rationally inclined towards simplifying a system as much as possible for the "purest" sound, personal experience has shown me that inserting a GOOD preamp between a source (w/volume control) and the amp often resulted in better sound.
Since I listen to music instead of theory, measurements or specs, I keep the preamp in the system.
