When you compare the differences in the recievers, one thing that sticks out is the warranties. Most have a least one year. KLH, 90 days. That says something about quality. The main reason for weight difference is usually the power supply, which in a reciever is usually the heaviest part. It's hard to believe that the KLH wieighs 7 pounds more than the Kenwood. Best Buy has been know to make mistakes in these specs. Maybe the KLH is including the packing.
