For instance, my personnal policy is to stay on improved habits, i use a plugin like vintage warmer, from decades only because i'm experienced on this one from decades
I's love to include new technologies, like some of the zynaptiq ones (Intensity) or from newfangled audio (EQuivocate) ...but would neeed some advice on how used them in conjonction (or not) with other plugin oriented mastering process, when they might redundant one some aspects (and not others) etc, etc...
So comes this question in my mind that a dedicated forum dedicated to mastering process might be relevant ?
It's all up to you !
