Actually, in the higher ranges he sounds much like Kaito V1, and its all to do with the upper ranges not having as much differential room compared to lower tones. There is something I read about this but basically, lower ranges due to how the wave length works have more room for differences then higher, because the wavelength of higher pitches produces small/faster wavelengths. Or something like this... Its been about 5 years since I read it and I never grabbed it for the wiki because it wasn't actually that useful.

But their lower ranges are very different.
