hello, does anybody has got the same issue with a a crackling sound coming from the center speaker in some movies, Star wars II (scene when chasing with the speeder) or with jurassic park III etc... it seems to happen whenever there is loads of music with at the same timea dialog. it will happen on every level of sound, it will not comeup from the DVD (listened with headset), swapped speakers and cables. Anyway, contacted Hifibitz abnd they sent it for repair received a new one and .........still the same. the only I haven't done was changing my coaxcial cable. Anybody can help me ?
