Okay, got the files onto my hard disk. Haven't listened to them yet. But in your accompanying email you mentioned that you noticed the distortion on only one channel.

Wonder if this has something to do with the Beta11 L/R bug? I think I'm hearing it in only one channel as well, but I'm running a beta that's not supposed to have the bug...

(And I did do all of the corrections in beta12, so in theory I should not have been saving a preset with beta11.)
