@bencat also, I changed the flac compression setting in the config file to the lowest option. You might want to make it higher again if you don't think it makes a difference.
Or if you like experimenting (as I know you do) you can rip some albums with the current setting, then rip them again with the highest compression setting. Then change the names in the metadata using a laptop with MP3Tag so you know which is which as they will have the same name (you can tell them apart in windows explorer by modified time) and see if you can tell any difference. Then report back as this is a disputed area.
