Benefits of 7.1
A couple of weeks ago I purchased an Onkyo TX-NR616 which is a 7.2 receiver. I have only ever used 5.1 before so the new receiver was connected to my 5.1 system and the extra connections I used to bi-amp my fronts as I listen to a fair bit of music too and thought this would get the best from the receiver in 2 channel mode. Ever since I got this receiver though I keep thinking about dropping the bi-amping in favour of surround back speakers. So I wanted to know if its worth doing this, does bi-amping make much difference, is 7.1 much better than 5.1?
