Fuses that matter.

Yes I think you are right Norm. Even when I don't think the fuse is directional, I still put it with writing as the direction due to my audiophile OCD tendancies.
But with the SR when direction was changed I could hear it easily. I would not say it was vastly better, but it was certainly a different sonic presentation.

This was quite a change to my previous fuse direction swapping attempts, where I was straining to hear any difference.

In response to Lacee's question, yes I do think the sonic signature of the fuse should be in synergy with each component. It is unfortunate, but like power cord comparisons a few years ago, people were saying this brand of cord is superior to that brand. As most of us know now, a power cord that sounds excellent on one component may not be very good on another component.
Same with fuses, in my limited experience. I have not tried the Audio Magic liquid fuse, but I have recently played with Hi Fi Tuning Gold and Supreme, Furutech, AMR, Synergistic, and one by Create, which has one end Gold plated and the other end Rhodium plated. So far, I am not much impressed with the Synergistic or the Create.
My opinion at this point is similar to Agisthos; fuses color the sound and are a hassle. I like the idea of a circuit breaker, which many manufacturers have chosen to use instead of a fuse. But don't go changing your fuses to circuit breakers right away...that's not what I am suggesting, unless you are really into it. And I do not suggest putting a metal slug in place of the fuse, as Agisthos and some others are doing. But that is up to you.
Sorry not to be definite here, but I can't be.
And the "Chips" ? I tried those on output transformers, and I must say the sound improvement is quite good. I have no idea how or why they work!

Hifi Supreme Tuning Fuse replacing main power fuse in integrated ARS Sonum-Filarmonia 30 watt E34L tube amp. Improved separation, more realistic all 'round. Not dramatic, but noticeable.

I just replaced my Classe' 2200 with a CA-2300. I was using a Hifi Supreme in the 2200 to excellent effect, but the 2300 has a completely different topology and requires the following fuse type:

IEC time lag, high breaking capacity 12A 250V

I cannot find this type listed among the Supremes' offerings, nor from Synergistic Research. Does any audiophile company make an upgraded fuse to replace this? Any suggestions welcome.

Vhiner, I would call the Cable Company which sells all of the fuses. They should be able to give you this information. I assume this is just a 12A slow blow fuse, but I have never seen that value.
