Agreed! I consider the performance between the 13700/600 and the 3080
to be the same...mediocre.
You can use the 13700 in a Mike Simms (EDN mag article) arrangement
and it rivals (IMO) any VCA, OTA, or discrete design I have ever come
across. At least as far as CV feedthrough goes and that's the most
important thing to me.
