I have a Denon 1803, Energy Veritas 2.1 speakers all around, and a JVC DVD player (can't remember the model). Sometimes when I listen to music (2-channel), the sound from the right front is very faint. Usually, I stop the CD and restart it and the problem is solved. Sometimes I have to repeat the process. It's not a dropout (if I understand what that is), as it's only in one speaker. Is this more likely to be a speaker, receiver, or source problem? Any help is apprecited.
