Best fuses for under $50?

Interrupting
ratings: 200,000 amps rms symmetrical

Time delay optional: Minimum of 12 seconds at 200% current rating.

DescriptionThe CCMR series is ideal for space saving protection of motors up to 40 hp*. It was designed specifically to withstand sustained starting currents of small motors. The CCMR 60 fuse is the smallest 60 A fuse available rated at 600 V. Compared to other UL Listed fuses, Class CC fuses are the most current-limiting, rating for rating.Features/Benefits• POWR-PRO® Performance• Extremely current-limiting• Ratings up to 60 Amps• 300 kA Interrupting Rating (self-certified)Applications• Motor and motor branch circuit protection

the best non pricey fuses are the ones with the highest ’interrupt’ peak ratings. Ie, time delay with very high peak currents, at the same time they blow at low sustained currents.

Littlefuse, cooper/bussman, schurter, SOC (one of the originals, that’s why they are in what is approaching.. 40 years worth of almost all Japanese amplifiers), and others.

One must be careful though, as they can mess with their warranty and more, ie, house insurance, and more...if they start playing with fuses that are not meant for the application they are being used for/in. That’s why the fusing info always says "replace with same TYPE fuse ONLY".

I bought the excellent Hifi  tuning Supreme at DAH Audio, - Black fuses for just over $50 each 
Very good  just give them 75-100 hours.

$300 might buy one a better amp, or at least tubes for one. And definitely some room acoustic treatment, or isolation footers. You know, stuff that actually provides improved sound ;-).

+1.
Only the gullible get drawn into this, with expectation bias.
