I think we can agree there, assuming that we're on that same page as to what "sufficiently high" is. My take is that almost all newer designs have DF in excess of 200 or so, which is plenty of safety margin for any sane setup.

The "small loads on the speaker cables" comment loses me though. Elaborate?

Long runs of skinny cable. 8-)

Well, as far as I know te amp can't fix that. It can mitigate it, but not enough to matter. An amp with a damping factor of 100 on a system with 0.25 ohms wire resistance would give about DF=24, whereas the same wire with an amp with a damping factor of 1000 would give a final result of 31 ... not a huge improvement for an order of magnitude boost.

On the other hand, just getting bigger wire, say, dropping the R to .1 ohms on the 100 DF amp would give about DF=44. Most modern amps don't contribute that much to the equation unless you have gigantic or very short wire runs. For sure, the new Outlaws are plenty fine.
