hi all, I just bought a second hand MZ-S1. I recorded some MP3 (high qual.) through USB from my PCat LP2. If I play them on the MZ, I get some really annoying crackles and hisses. I repeated the process on 2 PC' using Sonic stage 1.3 and Real Player, no difference. I did not yet try to record from cd player, but I listened to some pre-recorded stuff which sounded fine. I used a new sony md. Any ideas would be fine thanks stefan
