Synergistic Red Fuse ...

As far as fuse direction, if your have the sa11 s2 the s I'd on the power cord side, the r is on the transformer side if that helps.

Tzh21y,
The Red fuse is very good in my components  however the Black fuses are an improvement across the board based in on my listening. 
They're worth the modest increased cost.

Thanks for the info. Actually it doesn’t help me too much except it gives me the opportunity to point out a few things and try to clear the air a little bit.

1. The Synergistic Research person mentioned on another forum that his fuses should be tried both ways.

2. For some reason people have more or less assumed that the letters written on the fuse should be oriented so that when reading the letters right side up and left to right the letters should point in the direction of the signal going away from the wall toward the speakers in whatever component including the speakers themselves the fuses are located.

3. Sometimes it’s difficult to tell looking at the fuse depending on whee it’s located in the circuit of a particular component or even if the fuse is located where the power cord comes into the component which is the correct orientation for the fuse.

4. Some fuses have no writing on the on the main body of the fuse.

5. Therefore, all things considered, the owner must try the fuse both ways and determine as best he can which direction is correct. The letters on the fuse, assuming there are any, should be used only as a *guide* when switching fuse directions so as not to lose track the direction the fuse was just in. For fuses without lettering use a permanent pen of any color to mark one end of the fuse so you can keep tabs of the fuse orientation when you switch directions.

6. In the case of those aftermarket fuses that are marked with directional arrows, I.e., HiFi Tuning and Isoclean, the arrows should point in the direction toward the speakers, but in some cases as pointed out above when the direction of the signal is uncertain then you will have to try the fuse both ways.

I just listed to it both ways and settled on the current direction.

That’s very good to hear. But, my good fellow, what direction is that? I thought better of making a joke about the "current direction." When you say you "listed to it both ways" is that some sort of Freudian slip related to UL listed fuses?
