Interesting, of course the problem with a passive design is that it is always taking something away from the signal and giving nothing back. Almost all active preamps first attenuate and then feed that attenuated signal into a relatively high gain section and then out to the amp. This means that the full drive of the preamp is going into the amp and not a resistor before going to an amp.

This could be why you were losing the decays earlier with the passives. It takes a VERY good preamp not to smear the sound somewhat on leading edges and most are not up to it. I had one of the best passive pres ever made (little known company called Purist from Germany) and my Silvaweld preamp still walked all over it in terms of tone and dynamics, although maybe not leading edge transients.
