Whoa--don't confuse continuous power with "dynamic" power. They are very different things--and neither is terribly meaningful, frankly, the first because music isn't continuous and the second because there's no standard definition for it.
I'd say the NAD would likely give you more oomph. On the other hand, if the HK is working for you, you don't notice any distortion (and neither do your friends), and it doesn't seem to be running too hot, it's probably up to the job you're asking it to do. Basic rule for amps: If it sounds ok, it probably is.
