I decided to exchange the Pioneer 918 for the Yamaha 6160 before my 30 day exchange window was up. Best Buy in Canada has a sale and I basically got it for the same price as the 918. Powerwise, they seem to be similar. But the Yamaha has Pre-outs which I may use in the future. Plus, the Scene buttons will be really useful for my girlfriend who still doesn't know how to operate a DVD player.
