Hi,
As I've stated elsewhere, that "dynamic power" and "high-current low-impedance drive" is quite misleading. It may well have dynamic power and high current into 4 ohms--for about half a second, and then the protection circuitry shuts it down or imposes current-limiting that severely limits output power into 4-ohm loads so the output stage won't overheat.
That's usually what setting the switch to the 4-ohm position does: switches in the current-limiting circuit. (That is not true of the new NAD receivers, which will deliver their full output into a 4-ohm impedance.)
Tell your relative to get the M60s ( 8 ohms), which are an easy load for any receiver.
Regards,
