Hi Keith,
That will really depend on the use of the system. If you're mostly doing surround sound or theatre, you're probably better off using the power amp to feed all channels.
If you're going to be listening to a lot of 2 channel music, you're going to get more out of your towers, so you might want to bi amp. If you've got the extra wires to play with, try both out and see how it sounds in your room.
Thanks,
Tom
