Well, yeah got your point - mine remains. I like your idea of having the possibility to switch the metering point, that would be the solution for me.
And even much more I like your idea of relying on some plugins you know and not to switch to new ones all the time. Even if there is still the problem, that sometimes you have to update one link in the chain and this can have more or less obvious side-effects on the others forcing you to experience, be careful and find out again!
And I totally agree, that the PSP stuff is among the best you can get, as I never had ANY SONIC issue so far. And this is a very rare thing among all those plugins out there!
And back to the MasterComp: I wouldn't even bother writing here, if I wouldn't be so happy with this compressor. This is the only reason, why it bothers me, that I can't read the gain reduction the way it would be (still!) logic for me and that I can't set the threshold to -50dB.
