Thank you for your effort,
what can it be? i tried three sources: my pc, my notebook and my revo internet radio
and lazer is always the loudest. i also loaded your recorded file and its so boosted
and sounds overdriven on my computers. i only have this problem with lazer.
i made some screenshots from winamp, audacity and mp3directcut.
Its the file you posted and the signal goes most of the time to maximum gain.
sorry for the trouble, but i don't know what else i could do.
