I use all the Renaissance stuff far more than I'd like to admit.Less plugins - definitely. Strangely though I had more gear. Ha. But yes, you are probably right. If you know your tools really well, you can get a lot out of them (e.g. working with what I had).
I'm actually trying to narrow it down to my one goto verb, one primary eq, and a couple of favorite compressors right now for that very reason! I do not know my library of plugins as well as I once knew my old standbys!
EDIT: I've also refound a fondness for Waves Renaissance EQ6 out of all of the EQs I have. If only the GUI was bigger...
