They are rated at 89db. I'd call that medium efficiency. You do need to keep in mind that doubling the wattage only gains you 3db. Perceived volume increases with every 10db increase.
The NAD is rated at 80 watts. That's ok but not a lot. However, to hear a difference you will need to at least double that.
As said by some of the folks above, wattage isn't everything. Large power supplies, dynamic headroom and such make a difference too.
