Power ratings can be a messy business.

Interestingly the MATCH amp/DSP upgrade for an iD7 based HK is technically a D class amp.

Headroom equals the old saying that everyone's mileage may vary. In my world I push any audio system to the limit and at least with the wife's X5 HK system with the 600W amp have yet to be disappointed after negating the Logic 7 DSP mode.

Anything is possible along with the ulterior motive of cost savings.
