An amp such as your A21 should use a heavier gauge power cable since it draws much more current than a source component.
As you stated, that AQ cable is suited for source components which draw a low amount of current.
A large amp will never perform at its potential using a cable that can't deliver the current required.
If you are on a budget, take a look at Cullen Cable or Signal Cable for a PC suited for a high current amp.
