Depends where you use them, Fran. Inserted on basic channels, every DAW for ten, twelve years has had full delay compensation (and I doubt you've even DONE parallel compression, where the compressed signal is mixed back with the original), but it's only in the last few years that groups, sends and FX busses have got this feature. If you ever HAD mixed delayed and non-delayed signals back together, trust me, you WOULD have noticed it.
