X1pro does a nice job on mastering,but I find Sony SoundForge 8 much easier,
and very inexpensive,and yes I love the adobe products,abit pricey after buying all the plugins,
and programs availible from cakewalk,z3ta,rapture,dmpro and extra libaries,notion3,amplitude,guitar rig,
all the pro channel toys,so after all that it nice to just get down to a easy mastering program like sound forge.
(SF8 won't read 64bit files ,but your rendering to 16bit anyways.just render before you import.
