Dave, you are 100% correct in your 12/26 post, the black fuses sounded glorious for the first 10 hours, then yesterday and today at 11 to 20 hours, the system sounded mediocre, comparable to mid-fi solid state from the 80's, tonally thin, undynamic, shallow soundstage, hashy, etc. (both fuse directions). I cannot listen to this so I am taking Frank and your advise in keeping my big tube amps on until after New Years (4 days continuously). I hope the fuses break-in sounding at least as good as when I first installed them.
There is a question which I haven't seen answered. Do large amperage, slo-blo fuses take longer to break in than low amperage fast blow fuses? Frank suggested it may not matter when I asked him due to the graphene and other dampening compounds which take the same amount of time to break-in.
Lastly, I would greatly appreciate a company that breaks in their products. For the fuses, I would gladly pay 50% more instead of burning up my tubes waiting for the fuses to be listenable.
