This great system can be made better by upgrading the speaker wires and attaching a cooling fan to the top of the receiver (just a precaution)The sound calibration system is awesome .It will take some experimenting with speaker placement,but wow.....once you get it right,you'll turn into a braggart. Friends and family will refer to you as the guy with the awesome sound system. Neighbors will hate you (jealous)..
