I've been going a little nuts as I'm sure quite a few on here could appreciate swapping caps in the signal path of my preamp. I've had great differences with LCR Polystyrene, Amtrans PP, CDM Mica, and the ceramics which were in there. PP can be very detailed but bright, styrene smoothner but maybe not the most accurate and veiled somewhat. Interested in some of your favorites - 100pF is my value.
