So, i started with just the jfet and the 1n across the drain resistor that you first mentioned, and provided the sim and frequency response of that.Then, i looked at some different u87 style NFB de-emphassis and changed it to a 1M/470pF across the drain resistor. Both ways sound different, with the 1nF cap seemingly killing a bunch of high-end and the 1m/470pF leaving more but it's kind of "peaky" still. I know i'm not going to turn this into a u87, but trying to make it more "smooth" and not as sibilant/harsh on sources while keeping "some" high-end is my goal. My question is, did I do the 1m/470pF thing correctly and is that the correct way to apply it?
