I was told by a best buy salesperson that there was a 7 channel reciever, that when hooked up to a 5 channel reciever would carry-over the power from the 2 UNUSED channels to the other 5 channels. Does anyone know what reciever he was talking about???pls help. In otherwords the unused wattage from the other wo channels would be divided up between the other  channels..He said its the only reciever that does this..!
