I think load is related to power or current. When the current becomes excessive for the transistors, Mac has a Sentry Monitor circuit. In a short circuit the impedance approaches zero requiring the amp to produce tremendous current. A speaker like a Thiel CS5i requires an amp like a Dag that is built off a 2 ohm tap so that it can efficiently (without stress) supply the current and watts. In my opinion, Mac amps should not be used with speakers with a nominal impedance below 3 ohms. Mac amps have tremendous advantages in that when the impedance drops below the nominal impedance they can sound very dynamic and have more bass. What creating a deliberate impedance mismatch does is carry a good thing to an extreme.
