I get a lot of people ask me how I get the Vocals to be so prominent in a mix, well the answer always depends on a few things, but one I can recommend is to use a mic pre amp.
Pretty much all audio interfaces have a mic pre amp built in, but in my experience an external unit works very well.
They don't need to be expensive to be effective, I use a Presonus Bluetube V2, a 2 channel unit with a 12ax7 valve (replaced with a Genalex Golden Lion 12AU7 tube)
https://www.presonus.com/products/bluetube-dp-v2it is possible to buy all sorts of fancy mic pres, Neve 1073's for example...
https://www.thomann.de/gb/ams_neve_1073_dpa_preamp_stereo.htmIt's also possible to buy emulations of them as vst's (I have quite a few) but to my ears they just don't do it for me.
The vocal sounds better, what do I mean by better? more clear, detailed, a lovely distribution across the frequency range, just how I want it to sound, compared to how it is when plugged into the Audio Interface, which sounds a bit flat, less detailed, I don't know why but it does. Oh yes, btw I don't go for the Valve distortion (hence the 12au7) I add that later, because it can't be removed if you don't want it.
I don't use expensive mic's just a few Rodes, Beyer Dynamic and AKG, no need to buy Neumann's for what I do (Neumann's in Studios sound great, but one needs to have all of the other ancillary equipment to that standard to get the best out of it...)
So when I come to produce my Vocals I have the best possible quality to work with, I have my own approach to processing vocals, so usually they are easy to mix and get right.
When I work on Vocal stems from other artists, I nearly always (not always) hear a difference to mine.
The other thing that I have mentioned before is that my DAW Magix Samplitude pro x5 suite has, a broadcast level audio engine, which is simply sublime in it's clarity, as used on it's bigger brother Sequoia 16.

Here's a simple explanation why...

I would be very interested to hear your opinions, tricks and techniques.
As always, hope this helps
