Upgrading Fuses

Vhiner... Just as silly.

There are some things that you don't need to try.

I am selling anti-gravity boots. Put them on and you can jump off a tall building without falling. If you don't believe they work buy them and try them out. If they don't work I offer full refund.

To say that fuses make no difference is to say that your system is not "high resolution". No audiophile will admit to that!

Jeff_jones... Traditional "measurements" usually report specific characteristics of the signal. The measured parameter can remain unchanged while other parameters change, and affect the sound. The significant parameter for audio is "how it sounds". and the best measurement instrument is the human ear. There is a way to make the ear measurement in a completely objective manner.

In the case of an interconnect...

1. Input a common signal to both channels of your system. You can use a real music signal.

2. Adjust gains and, if necessary, frequency response so that the signal measured across the hot terminals of the amps is zero ( a null). You can make this measurement using a meter or scope. or by ear using a headset.

3. Insert an extra interconnect in one channel.

4. Repeat the null measurement of step 2.

If the null obtained in step 4 is the same as step 2 the interconnect has no effect.

If someone thinks that a particular configuration of wire (or fuse) makes audio sound better, that's fine by me, even if I disagree. However, if that person makes (or buys) such wire, brands it, and sells it at a ridiculous price that is not OK by me.

Vhiner... My comments are about fraudulent advertising, not just about fuses. If the market were more than tiny the Feds would be after the charlitans.

Circuit breakers are appropriate for power amps, where overheating due to prolonged high power operation is not uncommon. Reset the breaker, reduce volume, and resume the concert.

In a preamp, fuse blowout is associated with some fault in the circuit, and routine replacement (if you have one on hand) without troubleshooting is not appropriate.

Vhiner... "Measure" the same.

As I have pointed out, the human ear, which we all agree is the ultimate judge of how it sounds, can be used to make a measurement of any difference between two audio amps by listening to the null across the hot output terminals. Since "difference" is what we are interested in it makes sense to measure (listen to) difference. Small difference is almost impossible to objectively detect in the presence of the strong signal. "Almost impossible" opens the door to subjective opinions as we see in this discussion.
