Will there be any 'Arrow' mark in a Fuse holder?

Hi Everybody, I am new to this Forum. Please clarify that,

Will there be any 'Arrow' mark in a fuse holder to show

the direction to fix a fuse? Will all type of fuses have

'Arrow' mark? I need the advices to upgrade the fuses.

In one of a forum, I read the following 'Message'as follows:-

"The fuse has to be parallel to the overall direction of the sine waves coming from the wall socket and into you audio gear. If they enter at an unusually steep angle, the top (or bottom) peaks and throughs will get clipped off or attenuated and you will get jagged or almost square waves in you signal. The resulting SQ will be harsh and grating to the ears. Prolonged usage may damage the speaker coils as well."

So, friends,please give me a clear picture to replace a

'fuse' in my Preamp and DAC. Thank you.

Regards,

Rhapsodi.

A bit of info here, at least about Furutech and Hi-Fi Tuning fuses:(http://www.6moons.com/audioreviews/net/net.html) (http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1261938237)

I'm pretty sure I'm on the verge of looking for a new hobby.

Rhapsodi -- As you can gather from the preceding responses, whether or not the orientation of audiophile-oriented replacement fuses is sonically significant is a matter of, um, some controversy. Whatever the case may be, though, the statement you quoted is complete nonsense. You will not damage your equipment if the fuse is installed in the "wrong" direction.

Why not try it both ways yourself, and report your findings as to any sonic differences you may perceive?

Of course, for your assessment to be meaningful you'll have to be careful to allow enough time for the equipment to warm up properly following being shut down for the fuse reversal, while not allowing so much time that extraneous variables may come into play. Such as changes in ac line voltage or ac line noise conditions; changes in room temperature; changes in ambient emi/rfi conditions (perhaps caused by digital equipment elsewhere in the house being turned on or off); differences in volume control settings; on-going burn-in or aging of system components; the vagaries of aural recollection; the fact that additional detail may be perceived upon a subsequent listening to given source material that was not perceived during a previous listening, even when nothing has changed, etc., etc.

Best regards,

I feel exactly the same way when I read some of these posts. No offense to Davehrab, but things like the quote below can drive me to the edge
