Does your lumia 610 speaker distorts the sound?

[SaulSantos]

From the beginning, I found it strange that If I raise the volume to anything above 25 it would distort the soun heavily. It used to bother me, but I accepted it as bad quality of the phone. A few weeks ago, my girlfriend bought a Lumia 710 and, while considerably lower, it doesn't distort the sound at all. Is it a by design fault of the Lumia 610?
