My thoughts on his mastering chain is the same as always. The more you do the worse it gets. He is a perfect example of overthinking. I highly suggest you watch Dan instead: https://www.youtube.com/channel/UCQnz5mUTDkGwKvIQ9uyqiXw . Also start listening to the mastering show by Ian Shepherd
His production might be great or mixing but redflags go off when you see this much going on. You only need to go that crazy when you have a horrific mix.
Instead of this.. Put on a limiter first. See how that in itself compares to the reference. "fix"/ optimize from there if needed
