The English and Japanese tracks sound good, but the Spanish track sounds a bit louder than the other two and a bit less refined than people are used to with dubs these days. It may be more related to it's original recording than anything else. For the Japanese track, this is a decent sounded stereo track that's primarily played through the center channel. Dialogue is clean and clear and without any noticeable distortions. Though the show is as of this writing eight years old, the animation was done in a style not seen as much today, with more flat colors and less of a flashy look.
Some areas are a little soft and there's a few nicks and spots of dirt here and there.
But where it makes it up is in the detail of the settings, the characters and the overall feel of the animation. There is a lot of good fluid animation throughout for a TV series of this age. Some scenes are just wonderfully done here, notably scenes taking place in the Raalgon empire. And other than during the opening sequence, I found almost no rainbows throughout the show, not even along the edges. This is a solid looking transfer, especially with seven episodes on this volume.
