dampfact on a receiver is always low, and 140 watts receiver pushed to the limit is more like 90-100 watts rms, the 140 is probably a peak.
Damping factor is a mathematical equation based on the ratio between amplifier output impedance and the speaker load impedance, from there it is further affected by the gauge of wire, and length of wire run.
So you really can't say any amplifier has a "low dampfact."
Plus, damping factor is really more of an issue for really large concert loudspeaker matrices than it is for home systems. Unless you're using very small gauge wire over long runs or running some extremely low impedance speakers (which the 4 ohm M80s aren't) or running a whole lot of speakers in parallel - it really doesn't become a problem.
