PPCB Mini JFET Buffer

The picture up in Post 6, after adding adding the 2nd buffer, I am getting some switch pop. I'm using a momentary switch to a relay, so the pop is likely a voltage difference somewhere. And it's interesting, it gets better the more I switch it, like a capacitor discharging.

In the below schematic, I have RPD-IN as 1M, but I don't have RPD-Out at all. I often see anywhere from 1M-10M for input RPD, and 100k or less for an output impedance.

Does this seem right?
