Default Low duty cycle for full bridge SMPS?

We are designing a current mode full bridge SMPS (CCM) for class d guitar amp supply.

On maximum power, we want the duty cycle to be low.(say 0.25)

This is because its well known that current mode full bridge converters can be made with a higher crossover frequency if the duty cycle is low. (higher crossover frequency = faster transient response)

Also, low duty cycle current mode full bridges are easier to make stable. (feedback compensation)

Do you agree with this, and if not please proove me wrong.
