well you have a full life in front of ya.
start pulling them out one by one and see what happens.
What's the value in lots of capacitors inside a line stage preamp?
On one system I am using a Conrad Johnson gat2, and it's loaded with Teflon capacitors and step attenuator volume control, vishay, and I'm sure lots of other lovely things going on. It's doing a great job.
But I have no idea how important all those capacitors are except that they store a lot of reserve power and are available to fulfill Power demands of musical changes. Maybe that's all I need to know.
