Do Fuses make a difference ib sound?

@xmbw4 You say you've done blind testing.  You had to shut down the amp, replace the fuse, turn the amp back on, wait for it to stabilize, listen again, and repeat.  Is your aural memory so good that you can remember incredibly subtle details that long?  Or is it just that you're inventing those subtle details.  

For me, as someone trained in electronics who knows what goes between a fuse and the audio producing circuitry, I know there is no way the fuse will make a difference.  I don't need to bang my head against a wall to know that it will hurt.

This is an easy one …NO, unless of course if ferry dust is involved.

I’ve found high end fuses to have make a difference for greater sound realism in my system. However, the delta has been small enough that A/B/A listening was required on almost all occasions, rendering improvement too slight to be worth the expense or effort for me. 
For just a touch more (or way less), the Swiss digital fusebox dials up a far greater leap of improved everything to the music I hear.

Thanks folks! I was thinking about changing the fuses in the back of my Maggies but after reading here i think I will leave well enough alone!

Great thread and a lot of good points were already made...

1. Fuses are directional. True in my experience. 

2. The fuse maker explanations defy logic. True to me anyway.

3. Blind AB tests are really hard to do and moving equipment around to get to the fuse in back can also make a small difference.

4. Why not try them from TCC to see for yourself? If you like, its a small investment relative to your system. 

In my experience fuses do make a difference once they’ve had 200+ hours of break in. Better ones make more of a difference. I use Synergistic and Audio Magic fuses and they typically remove some harshness while allowing for smoother, more detailed presentation. 

Why do they work? I dunno, but they do something. Obvious end-of-the-chain ideas are the little screen right at the end of a faucet that changes the way the water comes out after being in miles of pipe or having people line up to enter a building instead of all rushing in. I truly can’t imagine why fuses work, but to me they do. Maybe it is the fairy dust.
