Massive amounts of capacitance across the AC line will tend to filter out EMI to a limited extent, not so much RFI.
IF one were having significant amounts of EMI on their AC line, then the removal of some of that would probably make a positive sonic difference.
However, given that such large amounts of capacitance can be dangerous or even deadly, it would behoove the person inflicted with such EMI problems to track down the source of the EMI, and eliminate it at the source, or provide as much attenuation at the source as possible. Then, just a uF or two might suffice to clean up the left-overs.
The problematic issues with using such large amounts of capacitance directly across the full 120VAC line is one of the big whoopee deal reasons my Super Quick & Dirty Digital filter was so effective but without the downside of a large amount of leakage current: the filtering capacitors were isolated across the back-to-back secondaries of the two transformers, and so, the user never saw the leakage current at all, yet you could pile on fairly large capacitance for maximum filtering effect.
I am referring to this filter:

my additional "tweak":

Other folks have tried it using 1 to 1 iso transformers, of a size that does not limit the wall outlet current maximum (essentially a 2000W transformer). Have to use full AC line rated X caps here but it still has very low leakage current.
