TURN UP YOUR VOLUME. It's there. original.flac requires +27.38 dB track gain (according to Replaygain).
From http://www.wikirecording.org/index.php/Compression:
"What happened to my low Noise Floor? When you reduce the peaks of a signal and then add the same relative amount of makeup gain you are raising not only the instrument by x amount of DB, but raising the Noise Floor as well. While usually not an issue in quality recordings, it can become apparent when compressing quiet acoustic recordings, or recording with a low Signal to Noise ratio. That air vent you forgot to turn off in your live room could go from being unnoticeable to being an annoying hum if you compress and raise the makeup gain too much."
