Some of the "nasally" stuff falls upon either the way the vocal was recorded or the effect of the engine.

The "Power" is defined as having a strong treble and a base range. It means their tones don't wane going high and low in the octaves. due to the way the engine is, power-type vocals produce the worst LQ results (see Cul, Kagamines, Meiko Power). This is improving over time, with each new engine opening up new possibilities both vocal creation-wise and variety-wise. A lot of people tend to associate the more strong tone types with clarity, which annoys me because a vocal type can be unclear. The Kagamines act1 and Act2 display all problems between them.

Also some of the softer toned vocaloids are actually "power" types, but because they either lack the clarity people think power invites or the tone was too soft, they skip over them. :-/
