Not to get into semantics, but in that sense full-sided amps do make some headphones sound better than they do with portable amps (because they sound as they were designed as you put it).  So I'll go on a limb and say that the net effect of full-sized amps is to make some headphones produce better quality sound than portable amps at the same volume.  The biggest effect is in the bass, which requires the greatest force to swing the speaker membrane.  The higher electrical current creates stronger magnetic force, which is capable of making faster changes (of the first derivative) of motion of the speaker, reducing lag in the initiation of movement and producing tighter, stronger bass.

Well, that's pretty much what I said. But if it's a headphone that doesn't require much, if any power, then the power argument for improving bass is moot.
