Might happen with other models too. I have found what seems to be a glitch with Logic 7 Music on the HK. If I play song number 8 (I'm looking forward to joining you,finally) Right CD from Nine Inch Nails (The Fragile) it seems to have a decoding? error in Logic 7 Music. During the song a horrible rasping comes out of the rear speakers on certain frequencies (on a electronic background sound in the song). It not a rattle or something loose but sounds more like just noise that's being sent to the speaker. It occurs at any vol. These speakers have handled everything else, loud soft high low. It doesn't happen with any other surround methods, just Logic 7. This is off the original CD and it's not an MP3. Don't think it's my speakers as they have never given me any trouble with anything I'v played. Can anyone duplicate this or has anyone heard about anything like this?? Thanks in adv Pete.
