My receiver has a 6-channel output for connection to a power amp. If I took advantage of this facility, would I be able to biamp any biwirable speakers in my home cinema setup? I know that biamping is quite common in 2-channel hifi setups, but I have never heard of anyone doing it in a home cinema setting. Is there any reason why I should not be able to do this? Has anyone else had any experience with biamping their home cinema speakers?
