When I first heard the music videos on youtube, I felt like the sound was a bit better than the rips from the streaming service. I think they sound kind of harsh with not much space or air in the sound. But still good overall. In the videos Ayu's voice also sounds less loud. What Baernash is saying is all true. I have come to expect that there will always be a chance that a new album might end up loud and flat.
I wish Ayu would have continued releasing her albums on HDCDs after RAINBOW. I love the sound those offer.
