Unless you plan on cranking the amp to it's rated 60 watts, you won't have any problem. The drivers would distort and likely blow up or blow your eardrums well before you hit that point. You can hook up a 1000 Watt amp to the Omegas, as long as you're only using a few of those watts.
I'll echo that low power amps (class A, SS and tube) have returned the most consistently good results for me with the various Omegas I've owned.
But, if you've got the $ to experiment, just do it. Learning what works best for you only comes with experience.
As a general observation, I've found that class A/B amps don't tend to "open up" and sound their best unless they're pushed a little bit, ie beyond their first few watts for regular playback levels (maybe 10% of their rated output or so). Class D, like Class A, seem to have a consistent output quality until they are pushed near their limits. Again, these are my general observations, not a rule by any means.
