That's the problem with just swapping caps based on their capacitance you can get wildly different sounds. People assume its that's each film cap sounds different but really you've just matched capacitance and not bothered to match ESR as well- so in effect only done half the job.
Effectively it's just like adding or removing a little bit of resistance from the circuit, if you know the ESR for the cap as well as capacitance you can usually predict pretty damn well how one cap will sound vs. another. It's one reason why styrenes and teflons have the rep they do- very low ESR.
...and don't worry about FBR it really is recorded like that with lots of ssssss and ttttttt sibilants
