“Having just recently listened to the Denon AVR-S920W, the 720’s sound quality is nearly identical. The 7-channel amp outputs about 75 watts of power at 8 ohms with 2 channels driven. At first glance this doesn’t sound like much, but unless you have power hungry speakers or a large room you’re trying to fill with sound it’s more than enough. During listening tests I managed to push the volume of the receiver pretty hard and the 720 handled it well with little distortion.”
