synergistic research orange blue fuse direction.

Hello everyone. I’m new here. Josh.   I’m 45 and consider myself an audiophile. I got into quality music young and by 16 was building car stereos and speaker enclosures for IASCA & USAC competitions. I also went to school a bit for electrical engineering. (Not long enough unfortunately)  I’ve also worked at a recording studio as a tech and did a bit of roady work for a couple small electronic music artists. I recently revived my interest with my purchase of a used pair of Dynaudio Focus 260. My Schiit preamp, DAC and amp will be showing up in about a week. I’d like to think I’m not clueless and understand digital and analog signals and how they travel throughout the electrical pathways. I’m just having a difficult time understanding how a fuse with 60hz AC power running through it could change the sound of the music.  I understand having a dedicated circuit breaker, large wire and a good outlet would help, and even starting to understand how a good power cord with well equipped ends would help.  But.... a fuse?  I’m trying to make sense of it. I understand it’s the one limiting factor in the AC power transfer from the cord to the internals.  And...directional?! How could that possibly change the sound? I do listening tests with every small, single upgrade of any piece and I definitely have an excellent ear for sound. Any insight and/or recommendations would be helpful. My ears and mind are open....
Do used fuses get put up for sale often? I’d love to actually hear for myself the difference between crap and purposeful design. 

@f1status1  Fuse benefits and their directionality are not a real thing, but the nastiness and name-calling of their proponents is very real.  Do not try to reason with common sense or solid engineering - if Synergistic Research says the sky is green then you are an ignorant moron if you don't see it that way.  Find another thread that may have some merit, or continue to monitor this one for its entertainment value.

Well of course one could do all the Deities a Dervish like homage by spending your money, take the product, bend over looking ever so diligently true North while noting the proper fuse holder aperture, insert said fuse into ......, stand up carefully allowing head to under body part clearance, praise yet again those Deities, flick the power switch with  your most devil may care nonchalance; safe in the knowledge you've done your directional neutron proton transfer function BEST!

 Plus you paid through the %%5** to do it! ;-)
Thanks everyone I really had an uproarious chest filling laugh reading many of these threads; and a bit of true wisdom dust sometimes gets posted too. ;-)

cheeg:

OK, I’ve been waiting for someone else to ask the obvious “dumb” question, but since none of you are volunteering, here goes: if it’s an AC signal, why does the directionality matter?

The idea being, since its AC its alternating, back and forth, forth and back, what's the diff? That about it? In a nutshell?

Okay so well first off in a house wired 120v the panel has 240v coming in with the breakers on the left connected to one 120v leg, the breakers on the right connected to the other 120v leg, and the 240v breakers taking up two spaces because they connect to both legs.
 
Got it? Okay. So even taking the back and forth point of view they are not all the same. One swings one way. One swings the other. (As Seinfeld might add, "Not that there's anything wrong with that.")

But what about 240v? What about the (admittedly rare) systems like mine where 240v steps down to 120v? There is no "leg" with a transformer. 

Well the answer is even then the power coming in one wire is positive, the other ground or negative. In any case the AC coming into all components, the first thing it does is go through a transformer (to get whatever voltage the component uses) then to some diode rectifiers and then to some power supply caps. Because all components, even though plugged into AC, they all run on DC. But you knew that, right? ;)

So there's your flow.
