as I understood the original version needs much more pressure applied to
achieve the same output voltage.
I think it's a quatization problem. I put a simple LP filter in there
and it got much better. A lag processor like Tony's Little Lag or a
MOTM-820 should do a good job on this.
I did a frequency analysis on this and think the noise is from
transients caused by quantizing.
As soon as they're smoothed out it's virtually gone.
