I decided on purchasing the Yamaha 2400 and while looking at the wattage of my surround speakers (SS-1) I noticed that the speakers were rated at 100 watts continous and the receiver has 120 watts per channel. The other speakers are all reference series so I assume that they are fine. Should I pick the Yamaha 1400 which is rated at 90 watts? Any thoughts on this? I hope that this post is not redundant as I searched and did not find anything on this.......
