If you have to resort to biasing two channels or two amplifiers differently in an effort to achieve balance, where is the advantage of not having a balance control? It would seem the balance control would be much less intrusive. The other option is a preamp with a left and right volume control.
I think the bias idea is a bad idea. I would try balancing the room by rearranging furniture, window treatment, room treatment or whatever.
