Sim Audio W-5 Fuse blew half way on the pre amp

The fuse blew while listing to a cd at high volumes and it is frustrating, i am wondering if it has a negative effect on the amp when the fuse blows and would it be ok to put a lager fuse so this doesn't happen again, any comments would be greatly appreciated thanks.

Thanks guys for all the info I think I will replace the fuse with the original size and call sim, and if this happens again I will replace the amp with a bryston 14bst or classe ca 301 maybe less headaches thanks all.
