peaking at what, digital or ana VU? It all depends on the source itself.
Know your room and speakers, have good bass response in it, crank it to ~85 db and use your ears. Really that simple. I listened to a ton of stuff in my room after I got things setup proper. It took me about 3 months of trial and error with balance in my room that I'm comfortable to start getting killer mixes (with my kik and bass being one of my weakest points for my entire production life until recently). This is being from releasing about 50 records, and selling a lot of music. My bottom end sucked, but its about the song really in the end.
I listened to some of my older stuff and yea it was kinda a face palm on a few of em' but man some great songs with great heart. Really thats the most important thing, the song, the heart, and how it emotionally translates and brings people where you want them.
Gain stage your stuff, no reason to go full scale digital 0 even on the master bus.
In general my channels are 99% of the time digital peaked at -12 db across the board then I plan with the faders for balance, with sometimes the kik being the loudest, but it completely depends on the song, production, track, the kik itself, the bass, the musical content, how everything plays off of everything else...
I also make sure that the signal flow through my plugins are not getting hotter than ~-12 db digital scale. That alone was a HUGE time saver for tail chasing with balance.
Note, if you mix at low volumes your bass end will be sh*t, if you mix at 85 db the whole time your percussion will be too loud so mix that very quiet, and getting mid range right at a comfortable medium range level. You'll have to mix in a various volume levels, but kik and bass have to be pushed loud to get the big picture.
Fletcher Munson Curve is your friend, and so are Radio Shack db meters with knowing sound pressure levels too.
When your all said and done, and your stuff sounds really good and balanced across the board at ~85 db in a room you feel confident in your mix will really translate well balance wise.
In fact it will kick major a$$ at 110 db. Knock heads off down the creek as they say in Texas.
lots of practice.
you'll beg for death
many times prior to getting it 'right'.
human suffering knows no bounds when it comes to getting kik and bass balance.
