Hi Fi Tuning Supreme fuse-Burn In?

auxinput:
A very nice description of just some of the changes that can be made to improve the sound a fuse imparts on a piece of equipment. 

The main point to me is that all the power goes thru the fuse and different fuses can have a significant affect on a system's sound.


dlcockrum definitely brings up a good point mentioning the Synergistic Research Blue fuses. I also agree they have a very positive affect and with their being on sale and having a great return policy, this is a good time to give them a try. They have been a major upgrade in my systems.

For people who have massively built power supplies such as the Nelson Pass First Watt 7 Amplifier, it's sound significantly improved when I replaced the stock fuse with a Synergistic Research Blue fuse. 

I found this to also be true when I put a SR Blue fuse in the PassLab INT-60 amplifier.

Congratulations on your modifications. Certainly a lot of thought and effort. Nelson does encourage the audio community to take his First Watt designs and see how they can be improved. 

I do still hope you will try the Synergistic Research Blue fuses in your amp. It is a simple experiment to perform and the cost is only the cost of return postage. The results will be informative reguardless of the results.

I would give your fuse change 100 to 150 hours of having a signal run thru it. Also, you should try the fuse inserted in the other direction to see if you like the sound better.

If your sound is still too bright, I would suggest buying a Synergistic Research Blue Wall Outlet that is sold with a free Blue fuse. This combination will improve the details and soundstage and yet the music will be more relaxed and have better flow. The emotion of the music will increase and so will your enjoyment. I have tried the HiFi fuses and while better than most original equipment fuses, I now use the Synergistic Research Blue fuses.

And if you do not like the change in sound, you can return them for a full refund.

Absolutely correct. Anytime you have access to a fuse that was not been tested for the best direction it is a worthwhile  experiment to listen with that fuse in both directions.
