Krell lists an output impedance of 0.17 Ohm.
DF equals speaker impedance (of 8Ohm) divided by amps output impedance.
In the case of the Krell that gives ca. 47 (a pathetic number really!).
Rotel states a DF of 1000 for RB1080. Neither states at which frequency, it should be stated at two or three (100Hz, 1Hzk, 10kHz for example). DF tends to decrease as freq. rises.

Guess the Krell might have a higher resale value tho'…
