I have a powercore as well.. The compressors on the UAD kill the powercore. I also just tested all the Sony plugins.. After reading all the good reviews I was a little disappointed. The oxford eq clips very easy when you are trying to push the sound. The Cambridge EQ on the UAD has MUCH more headroom reminiscent to analogue gear. I like the powercore for it specialized plugins though (reverb...erc)... and the soon to come VIRUS..!
