Default metals!

Just for interest!

I know that everyone will sigh!
However I wondered what people think with regards the questions:

Linked to "I will believe it if I can measure it!"

I would like to ask what people think regards

1. Solder containing silver as or opposed to lead tin Etc

Which is the preferred %?

2. The cable question, silver plated PTFE or Teflon insulated as opposed to copper linear crystal / oxygen free copper.

Can you measure a difference in sound?

If not why not?

Regards
M. Gregg

I will make a comment.

I tried a piece of gold wire in the input of an amp. It sounded dull.

You're just trying to get some laughs, right?

Any time two dissimilar metals come in contact a galvatnic and thermonic junction is formed. Above 0 absolute it will produce noise.

With regards to cable, given sufficiently precise equipment, I'm sure you can measure a difference.

The resistance will be different, the capacitance will be different, the characteristic impedance will be different.

These will all impact how the cable interacts with the output and input it is connected to.

Whether or not it makes a difference in the sound that is produced is another matter, which is very subjective.

I use 60/40 rosincore and good quality wire.

1. It depends on what you're trying to solder.

2. Very easy- the dielectric constants of the insulators will be different.

I know that cables can be directional.
That skin effect seems to alter "frequency response"
Diameter seems to also have an effect.
Dielectric also has an effect on "sound" this is the case with caps PIO, polypropylene etc.
The number of crystals and impurities can change "perceived sound".

When I tried some solder from "Audio Note" the sound seemed different when I ran out and used a silver mix!

Can this be measured?
Or are we fooling ourselves if it can’t be measured?

It's unfair to come to any conclusion until you've given the wire time to "burn in"

(about 5000 hours should do it) -

Yes I agree what takes place?

If you want a "Vintage" sound just drip some candle wax on a circuit board!

Or knock a pint over onto the speaker. The damping factor will rise 15 points if it's Bass. If it's Guinness, you'll get >20!
