Using the preferences window, try editing your EQ settings: low EQ should be around 60-100, high eq should be around 2000-4000. Also try using the regular EQ mode, not the simple low-cpu mode.
Your replay gain boost of 9 is really high. Try 4 or 5. Also try reducing the vinyl gain to 1 (you may have to directly edit the file to do this). Any one of these settings might be causing the issue, so I'm hopeful this will nail it. We might need to change the mixxx preferences to enforce better ranges for these values.
