In general, I would say it is not a good idea to plug a power amp into a pre-amp or processor as a power source. Better to plug everything separately into a device designed to provide good clean power to other devices, in particular to a power amp. I've found even a mid-line power strip from say Monster that may cost a couple hundred new these days does a pretty good job providing clean power that results in improved sound, usually in terms of detail, transients and soundstage accuracy. I use such a device from Monster with a Musical Fidelity 150W/ch amp rather than plug the amp into my pre-amp for easy switched on/off.
But still it might be possible.
Check the output power rating on the processor first compared to the amp power consumption to make sure the amp does not draw more power than the processor is capable of providing.
