Here's a question for you old farts, audiophiles, and EEs: What are the appropriate uses and benefits/disadvantages of all the various types of capacitors? For example, electrolytics are often used in power supplies. I suspect that polycarbonates are thermally quite stable. I am curious about ceramics, tantalums, electrolytics, metallized and foil film capacitors with mylar=polyester, polystyrene, polypropylene, polycarbonate, teflon, etc. Please post to the net. Jeff Chan Summer intern at Relation Technology Inc. (and audio hacker) P.S. not to start any controversies, but I have heard audio differences between electolytic and polypropylene dc blocking caps in disc players. The film caps were pretty close, and the 'lytics did bad things to sound. You can *easily* test this yourself. Just put some big caps on a switch in series through a tape loop and switch them.
