Audyssey has terrible processing.Denon always sounded flat and inaccurate for music. I even tried the multi eq app and it never worked to my favor. $20 gone waste, seriously.\n\nHuh. My experience was the opposite. I've found Audyssey blows ypao out of the water in terms of accuracy. The app editor is just icing on the cake. You have a lot more flexibility and options for dialing in your sound. My music sounds fantastic now.
