I'll try to up them tomorrow. It'll be slow.
Ok, I've upped some files to the FTP. They are piovrauz-GAIN.flac, piovrauz-GAIN.mpc, piovrauz-GAIN.gif, piovrauz-GAIN.txt. the .gif contains the screenshot of my DSP config and how it changes during playback, the .txt is a detailed explanation of my issues. Btw only .mpc are affected, .mp3 are not (checked).
