I got a sneak preview DVD today of the first episode dubbed. I'm glad they left in the original opening and ending songs. The scripts are pretty accurate with the Japanese version.
Hikaru's voice takes a little getting used to, it doesn't suit him perfectly, but it's okay. Sai's voice does not suit him in my opinion. I enjoy the VA doing his voice's voice, but I don't enjoy the voice on the character himself. Akira's voice is decent. Akari's voice voice is one of the few I found that fits perfectly.
Overall, the dub is a pretty decent dub. I'd give it an 8/10.
