Littelfuse. If you want to spend some extra money they now have audiophile fuses. Stick with the pros.
No claims whatsoever for any better sound quality, seems more for medical to me.
Just higher glass breaking strength if in mobile conditions.
Fancy gold or rohdium plated end caps to better resist corrosion, if in humid conditions.
$10 in "slow blow only". DO NOT USE THEM TO REPLACE FAST BLOW FUSES
And guess what they are Orange🤦♂️ Put SR on them and sell for $150😵😵
