They can be super at getting rid of RFI. Like you say, they have excellent ultimate attenuation at high frequencies. I routinely use similar ones along with feedthrough caps for filters in gear for repeater sites.
However the highest perm material is pretty non-linear and if you maximize the cranks they have loss well below 100KHz which is getting rather close to hi-fi for comfort. So, at the risk of stating the obvious, I suggest that you listen to make sure that they don't adversely affect the sound before permanently installing them. If they do, and your interference isn't too low, go with ones with less perm, besides being less reactive, they will be more linear.
Glad to see that you are trying to address problems at the right points in your system.
Regards, Rick
