Don't Norge Amp has fuses in rail? I remember seeing in Norge Amp.
Its different topic how far it serves purpose but its there. Now relay based protection has some peace of mind but not true always, specially for Chinese ones which suffer fused relay contacts and stuck relay. Because when DC flows through speaker, it may weld relay contacts. In some cases faulty implementation or improper copy of original. That's why i designed my own PCBs for protection, either preamplifier or power amplifier. It does not cost more than ?350-400 but you can choose quality parts.
I don't have experience with diyaudiocart speaker protection but will try one day.
