Hello Organorak,
If you want to see your headphones go up in smoke, connecting them somehow to the outputs of your 200W amps would do it, they'll be crispy critters in no time. That or the first time you put them on connected this way it won't matter anymore anyways, because you will likely be completely deaf afterwards!
So your amps have no headphone jack on them I take it? I also have a 1010LT but have not tried connecting the headphones directly to it, mainly because I rarely use them and my neighbors are far enough away!
I know others here are connecting to the 1010 but I think the signal may be a bit weak, thus the need for the headphone amp, probably makes it easier to connect them as well without special adapters and I wouldn't doubt there's a volume control on the units as well. I'd say if you have the adapters needed, try them connected directly to the 1010 and see how it sounds, can't hurt. Don't forget, you need to create a mix down channel for your headphones in order to hear everything in stereo.
Regards.
Marc
