I recently got a new Denon receiver with this feature and used it to set up my speakers. I have always done it manually and when it was done I was not happy with the sound. I read through the long q and a post and re tested as it recommended with similar results. It also said my left front speaker was out of phase and the levels for this speaker were way off. I then pulled out my Avia test patterns and with the phase test it seemed like that speaker was out of phase so I double checked the wires and the speaker was properly connected. I am not sure what to make of the problem. I then went back and reversed the connection on that speaker and manually calibrated the system and it sounds good but I would like to figure out what is going on. Any thoughts would be appreciated, this is my first receiver with Audyssey but I am not new to HT and been using these speakers(DIY Adire setup) for 12+ yrs now with no problems.
