Ahh, THAT kind of bi-amping. Using a separate amplifier (with a separate power supply) for left and right channels...

Again, that used to make a difference but nowadays my understanding is that most medium and high-end AV receivers run separate power supplies for different groups of channels to accomplish the same effect.

Bottom line is that it is still hard to beat getting all your components up to roughly the same level in a straightforward system before you spend $$ on anything non-standard. Exactly how and where you spend your money will depend on what you listen to and what your room is like, but if you're going to do anything out of the ordinary then IMO you should spend time and $$ improving your room acoustics first. It's a tossup between speakers and room re: which gives the most benefit per hour or dollar spent -- electronics are not going to have anything like the same effect.
