What's going on with Synergistic Research fuses?

Again, for the umpteenth time, fuses do NOT affect sound in ANY way.

If you think otherwise, you are either delusional and/or very gullible to the power of suggestion from marketing folks.

If it was otherwise, dont you think manufacturers of audio equipment would already put a "boutique" fuse in there since their reputation is on the line and there is so much competition between them ? Would they try and save a few cents on a device they are selling for thousands of dollars, and jeopardize their "sonics" ?

If you do not believe the engineers, at least think about it.

Exactly, boring going over the same pixie dust with no engineering basis.
And I have tried it, many times.
You are either from another planet, or have bionic ears.

Another snake oil subject. I do NOT believe power cords matter either, as long as they are within the required current specifications of the device.

Again, double blind test.

None exists.

Modern science requires verification, measurement & proof.  None exists for power cords & fuses.  What everyone has here is SUBJECTIVE evaluation.

@cal91
if you have noticed so much improvement in your sound then obviously you should keep your fuses. 
We will just have to respectfully disagree that the effects are not universal but very personal, and that standard measurements do not show and explain the perceived difference. 

Only one proof for all this:

Double blind test.....

None exists.

All the best to u too.

Oh and... cold fusion exists.

I build amplifiers at home as a hobby.  Over the years, I have built about 6 and given them to my friends.  The ranged from 25 W/ch class A to 400W/channel class AB.  I am an electrical & electronics engineer who graduated from UMIST (in the UK).  I am currently a senior software (low level firmware) engineer working at Broadcom working on 5G and 11AX wireless.  So, I know a little bit of how electronics works and how I can measure things.  I also DO trust my ears.  I have an older Cambridge Azur series amplifier on which I performed the fuse tests.

I connected a scope to the speaker outputs and used a 1khz sine wave input and I replaced the fuse with the following:

- straight silver wire 12 awg (no change in sound, no change on the scope)
- straight 99.9% pure OFC copper wire 10awg (no change in sound, no change on the scope)
- standard Romex wire used in the house installation (12 gauge 20 amp circuit) (no change in sound, no change on the scope).

Even with a complete short circuit of the fuse there was absolutely no change in the sound and/or signal.

Are you guys saying to me that "your pixie dust fuse" actually introduces some magic into the AC line that even a straight thru silver wire short circuit cannot ?

That is why I KNOW all this is bs.

@rodman99999 

It is not just my ears.  It is also my measurements and the engineering norms.

I guess you believe your ears and so do I.  I also believe my measurements and all the engineering knowledge that I have accumulated over the years.

As I said, we will have to respectfully disagree and that is the end of that.

At the end of the day, it is your money, your purchase, you can do whatever you want.

Cheers
