Hi Fi Tuning Supreme fuse-Burn In?

Thank you, auxinput2.  I had a similar experience, also.  But, was not sure if the difference I was hearing was because I was using a larger amperage fuse or because I had changed the fuse type. 

What is your thought and recommendation on doing this (using a larger amperage fuse) on tube equipment?

sorry, I can't comment on tube equipment.  I don't have any experience with that.  I would imagine that you want to be very careful about keeping the stock recommended fuse values.  On tube equipment, the 115/120V AC voltage actually gets converted to a much higher voltage, such as 250V or 300-400V to be able to drive the tubes, so a short in the circuit could have an even more catastrophic impact. 

This is the reverse of normal solid state equipment where the transformer converts 115V AC to something a lot lower - anywhere between 25V to 80V (which can be on some amplifiers).

Just got this fuse.....At first it sounded like it was out of phase, had a weird "phasey" effect on the sound, vocals has a weird reverb effect.
Fuse is definitely directional, one side is very peaky and treble heavy. The other is much more balanced. Over the first 30 or so hours, the timbre of instruments is constantly changing....I have never experienced anything like this. Tonality goes from warm to cool from one listening session to another. A total roller coaster ride.
The one question I have for the people that have used this fuse, what is the consensus for the total break in time?
And if others had similar experiences as I did.
Also what is the final sound signature that I can expect at the end of all of this?
Thank you for any help that you guys can offer.

I Have used Furutech, Hifi-Tuning, SR, Buss and other fuses, never found one sounding the same both ways. Strong suggestion: use graphene paste or other contact enhancers. The effect is strongest on fuses and fuse holders. My last upgrade was from Acoustic Revive ECI-50 spray to Mad Scientist Audio Graphene Contact Enhancer and it is a very significant improvement

I have some Deoxit on hand, will order some graphene contact enhancer right a way. Thank you
I left the DAC I am using the fuse with running 24/7 the last few days, (using pink noise) big improvement so far. The fluctuations in sound have eased up quite a bit. I have never heard such a clear burn in for a fuse like this, at times it just sounded wrong, but it’s coming along very nicely.
