The ’blowtorch’ thread over at DIY audio was and is full of audio designers. Fuses and circuit breakers were and are topics of discussion.
Circuit breakers are preferred due to their ’least’ level of sonic interference.
Fuses end up being the item of choice due to the manufacturers, not the designers. Fuses and fuse holders are much less expensive than circuit breakers.
Since one has never heard the amplifier they own with circuit breakers instead of fuses..the question remains...but as a question that is non existent, unrealized, unasked.
Thus the manufacturer saves the money or costs of 4/5/etc circuit breakers of optimum quality, per standard amplifier, as they only have to buy and install fuses and fuse holders. Fuses...which don’t have failure modes like circuit breakers might....and any circuit breaker problems (ie, unknowns, and we don't want unknowns) stay off the manufacturer's plate of after sale issues.
