Happy with my purchase, I decided to import it into iTunes. I'd upped the bitrate to 320kbps and max'd the sample rate for increased pleasure and enjoyment.
I listened to it, and it didn't seem to excite me as the vinyl releases had, which was odd as the tracks on Chosen Lords come from the vinyl releases.
Then it hit me, the volume's been normalised; they'd slaughted my snare rushes! All the tracks with delicate and fine sounds had been stream-rolled over, which happens to be all the tracks.
I then reimported the album without volume normalisation, and voila, the album was alive again. But what's more worrying, all the album that I've imported into iTunes have been normalised too. All those albums that I've thought "Yeah, ok, but it's not that exciting" may have been unduly affected by this stream-roller of a feature.
EDIT: I've just realised, unchecking "sound check" in preferences turns off the volume normalisation for all the tracks in your iTunes database; it's not permanent. And breath out.
Don't do volume normalisation, kids; it's a mugs game.
