Hey guys, i have notice a loud and disturbing hissing sound in the background of my player, which is hd5, and another Sony player, the bean thingy. Anyone else notice it or its just my players? HD5 is a really good player and the sound quality is top-notch, but the hissing sound ruin it all! I'm thinking to buy the new 8gb a800 or something but i won't if the hissing problem exist in all sony players as a drawback for the good sound quality.
