Guys, I had a tough time removing the banana plug covers from the speaker binding posts of Cinema 50. I could remove only a few. They came off without using any tools. For others, I tried with some soft tools but I did not apply too much pressure fearing it may damage the speaker binding post. So I have connected some speakers with banana plugs and some directly with wire, without plugs. I guess this will not affect the sound quality. Another issue I faced was after completion of Auddessy setup, when I was testing the system by playing movies, the amp stopped responding. At first, I didn't notice as the movies were playing but when I tried to increase or reduce the volume, it did not respond, even using local rotatory knobs or by the phone app. I switched off the system by unplugging it and then restarted. It responded to the remote and even local knobs started responding. I guess it was trying to update the firmware when I was setting it up, but since I had not paired it with wifi, it failed to update and got hung while playing. I updated the firmware and played some movies for about 30 minutes. it worked without any issues. I hope that was the reason. I found one YouTube video explaining the same issue. Has anyone faced this issue?
