Just a tiny remark to add:
I don't know about the 2045. But in attempt to characterize the 3320 and
it's clean-ness, "OTA based filter" might not be exactly right.
There *are* OTA based filters that add harmonics to the sound, depending
on the feedback resistor dividers. The CEM3320 (unlike the CA3080)
uses linearized gain cells. If memory serves, these are even current-in /
current-out multipliers, so the "transconductance" in the word "OTA"
would not fit anyway.
I don't know what a good word to characterize the type of 3320 filters.
"Linearized VCA based filter" should cover the character of its sound,
so maybe that would fit.
