What is the output impedance of the unit in passive mode?It is most likely that the filter effects of that output impedance is causing the difference that you prefer.
Edit, That preamp has a input impedance of 10k in passive mode. I will guess that the input impedance is higher than that when the preamp is in active mode. If your sources are not happy driving a 10k load that might be what you are hearing as a difference between the two modes.
