I invested in the Valhalla suit and use the Room modelled vst in almost every mix.- without reverb on each channel.
Normally, I use it as an Effect track, then send each channel to it as well as the output.
If you've got it right, suddenly, it sounds like everyone is playing in a "real" room - together - at the same time.
As I said, I'm still learning this technique but, the difference it can make is awesome.
Mind you, it won't rescue a bad or "muddy" mix
Complicated business this
