A watt is a watt but most amps are spec'd at continuous power output into 8 ohms. Just as important is the ability of the amp to deliver short bursts of power into lower impedance loads. Naim amps do this very well so they can play as loudly as some amps that have higher continous power ratings. I think they can handle it but you would have to try it to be sure. A lot depends on how loud you want it to play.
Of course you could go with the NAP 500 @ 140 watts, but the $22,000 price tag might exceed your budget.
