It's a mistakeIs that a mistake on the back of Heaven's Feel? Audio is listed as 2.0. Audio is 5.1 on the AoA release.
Blu-ray Forum - View Single Post - The Anime Blu-ray Video Quality ThreadThe Madman version is 32.7GB on a single BD50.
Audio is 1536 kb/s, DTS HD MA 5.1 16 bit for both tracks. I don't have high end equipment but it sounded fantastic to me. The transfer on my TV looked pretty damn good as well, fairly happy with the result. It has the MVM logo so the UK transfer is going to be identical. I'd love to have the Aniplex version to check if gamma is correct but as far as banding and artifacting I didn't see much if any,
