So you are talking about line level filters. Then the issue is the output impedance of the preamp and the input impedance of the amp and what effect they will have in interaction with the selected filter components. The active circuitry in an active crossover is not usually used for a gain increase but rather as a buffer that keeps the aforementioned interaction to a minimum.There is no simple answer as to which is better because each requires an implementation specifically for the given system. For example if the passive setup is not optimal in terms of impedance and the active setup is, the active setup may sound better even though it may add more coloration from the active circuitry.
