Well... back then they HAD natural transient control, and what people are reacting to mostly is uncontrolled transients that make a recording seem spiky and thin. So basically, for the same amount of control that those old records had, you're looking at a -9 to -8 in the digital world. NOT a -14 without any kind of transient mangling.
That about says it all for me.
Mastering 'hot' in the digital realm is a form of transient control, and as such there is a sweet spot for any mix. One of my earlier works I still regret when listening back due to the mastering level being slightly lower and my own transient control having been subpar in prior years. As a result the drums just sound way too spiky and harsh, with not enough actual body.
This is in fact a reflection on a massive problem that can be had with the widespread Slate samples. They are already so compressed, transient designed, and the attacks are so in your face that the additional slow attack compression people do just make their mixes sound like "dundun POP dudndun POP dundun POPOPOPOP" without incorporating some intense limiting, clipping, saturation or other forms of transient control. I know because I fell down that hole some years ago, and it took a little while to come back from it and start getting normal drums again.
One of the best ways I've found to get natural transient control back is to use the Alex B SSL programs for Nebula. The harshness and prominence of transients instantly diminishes, which is doubly helpful in the digital realm since ITB compressors commonly have very clean and harsh attacks. Staging these plug-ins on channels, busses and the master bus gives you an incremental softening and saturating effect which both increases perceptible volume and gives you more headroom to work with. Tools like this I've come to find indispensable when working ITB due to the 'clear glass pane ' nature of the medium.
