Capacitors in Nola Viper Reference III

I currently have Nola Vipe Reference speakers, which have Clarity Cap SA's installed in them. Does anyone know what caps are in the Viper Reference III's. I think they are some type of Mundorf, but not sure. Also, has anyone installed anything else in these speakers, and if so, how did it sound? I'm thinking of upgrading the caps and would just like to know what caps to install. Thanks in advance.
