+1. I use Satson everyday and have NEVER had this issue.
Check your gain-staging...
if you have say, 150 tracks with an instance of satson on each im sure youll end up with some noise but it shouldnt be at a super high level.... thats an extreme case.
VCC is much noisier (not a bad thing, imho) than SatSon and VTM even more so (again, not a bad thing and is variable!)
