Without the right monitors, you can't master.... without the right listening environment, you can't master... without the pristine signal chain that only colors a signal when you WANT to color it, you can't master....
So it's not "impossible" -- if someone invests in the creation of the proper sonic space, with the proper monitors, and the proper signal chain, it can be done in a home.... the reason I say it's unlikely is the cost of doing it... easily an $100-200K investment at a minimum. And then there's the whole other question of skill/experience.
It sounds like you think a piece of s/w can replace all the other requirements of mastering and sorry - that simply isn't the case........
