I somewhat thought this since the beginning, but didn't give it much thought until recently. The voices for the Aglaia raid bosses feel very undertuned, in relation to the rest of the sounds. At first I just thought it was a volume issue. But even with the BGM set to 35% and Voices set to 100% their voices are still drowned out by the other sounds in the raid. This is in contrast to the other raids, and specifically the other raids in the series, where the voices are a bit more prominent and aren't drowned out.

Is this an issue others have noticed? Or is there some way of rectifying the situation?

I don't remember there being an issue with them.
