Although your comments are addressed to @jasbirnandra I’m sure others viewing this are obtaining valuable insight. Not that yours (Or anyone’s) opinion is absolute but certainly it provides some general distinctions between the various capacitors sonic signatures.
Before deciding to commit to an expenditure on capacitors it is very helpful to have some degree of appreciation for what their sonic character/signature may be. For most it is not feasible to buy every single capacitor of interest and test them in one’s audio system. Someone such as you who has heard a large sample size of capacitors can offer meaningful guidance.
