your relationships are correct but I think your numbers are a bit off. There is a noticeable difference between a DF of 10 and one of say 100. But the difference decreases faster does decrese quickly as the DF goes up. A good place to view the affects are the Stereophile frequncy curves for amps with the simulated speaker load that John Atkinson does. Look for the variation from flat versus the DF(or output impedance of the amp which is effectively the inverse of the DF for a given speaker impedance).
