waves:
if you stick to the basic 'big-dog' plugs,
they are great.
I HAVEN'T USED a better more transparent limiter than the L2 (mastering plug only)
i use the L1 on individual tracks and busses.
that said, i haven't used the L3.
my guess is, i don't really need that.
the LMB comp is really nice....
i use the RComp, RdEEsser, REQ, MaxxBass, Doubler, Super tap, Liner Phase EQ, and that's all.
