Sony XA5400ES fuse directionality...

They can make a difference around 4k hz. Some people like that.

They make no difference. Try to return them if you can.

I appreciate the input guys. I did hear an improvement in clarity and improved background details with the one I put in my amp. It was a bit bright at first, but smoothed out after a couple of weeks. I also tried the new Nano Liquid fuse, and it really rolled the highs off substantially. The dealer said the Liquid fuses have "smoother, analog sound", but to my ears it sounded like everything above 10khz was rolled off. I sent that one back right away for a refund!

"Best way is to try both, and the one way which sounds clearly better is the right one."
are u serious? or joking?

fuse is a fuse - it does not make a difference in sound? also, direction does not matter, unless the glass enclosure will pickup some frequency....someone should check it...

kind of same as changing the power cords - did you ever looked inside the equipment and check what kind of wires the manufacture use between "super hi end $2000 power cord" and the rest of components inside???

Hak, it's best to leave the fuse people alone. I tried reason once.....like how IS ac directional again? to no effect but getting people POd. And yes, they'll have you believe in all sorts of weird stuff. Fuse Microphonics and diode effcts. Break in of a fuse. All the rest.
Leave it be for the sake of 'peace in our time'.
