are you talking individual tracks, or stereo mixes?
do you want high RMS average, or do you want to control peaks only?
do you want your music to be full of dynamics, and have wide ranging deep sound, or do you want it flat and undynamic like the majority of major label releases today?
rms energy depends solely on the source.
after that, if you decide to tame peaks before conversion, you will need an outboard compressor and/or limiter.
after that, once the signal is in the DAW, youi can further apply more compression, and limiting, to wrestle the RMS average into whatever range you see fit.
the point of all this, is to get your sound into the daw in a matter that does not distort, and does not bring up the noise floor (by greatly amplifying a weak sound)
me, i watch my peaks, and worry not about RMS
i track with peaks at -12db typically.
i also track with outboard compression.
sometimes i use it for PEAK control, sometimes i use it for subtle compression, sometimes i use it just for color.
