    I tend to like the polypropylene over the polyester but Joe may chime in..... Will it make a diff??? Maybe, maybe not, but that is the fun of it if you like to experiment. Most of all? Have fun listening....

    There are 8 polyester caps which you COULD change out (for polypropylene), but you may not notice the diff.... Shit, some caps change values during operation from heat/freq/drinking, and if you want to experiment to make your amp/Pre fit you system/ears... I say GO FOR IT or.... Maybe not... I experiment a lot.... Some things work, some don't. but, how ya gonna know... Sometimes, you can't find caps in the form/material/function so you get what you get.. Sometimes, the designer saved a few bucks.....

    Derek ,
    a question : "What about EMC ?"
    For instance , if you receive a call on your mobile phone when you are near to the amp are there interferences ?
    The plastic case is very nice and fantastic for isolation , but it' s not a shield for EMC .
    It's only a my curiosity .
    Ciao
    Marco

    PP is best but PE is not a bad choice either.
