metals!

[M Gregg]

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?

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.

 

[M Gregg]

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!

I silver-soldered up a set of phono cables made from pure silver wire and braid to quality gold-plated RCA plugs, can I hear any difference over my cheapies, NO, (your ears may vary)

 

[Mr_Zenith]

So... does that mean that if one has a "tin ear", what they really have is a 60/40 ear? And what would one have to do to achieve RHOS compliance?

Interesting!

This is what it’s all about.
Can you hear a difference with a change of cable under any circumstances?
Or solder?

 

[M Gregg]

These comments are here for criticism!

I am told that the junction between two metals creates a thermocouple. This has an effect on signals. This is why "High Quality" cables use a welding connection method so the metals "mix" to reduce this effect.
The impurities between the crystals of a cable also has the same effect and can make a cable directional.

Consider them criticized.

So if we wire with lead it would be heavy
If we wire in silver it would be bright.

LOL however is there any truth in this!

 

[M Gregg]

So do we think that dielectric is more important than metal used?
Which would mean silver in oil caps do not matter only the dielectric is important?

 

[M Gregg]

These are just comments.

Feel free to state your thoughts.

I would be interested if anyone has a preference to solder types.

The silver wire would be brighter and lighter
The lead wire would be duller and heavier

In my youth we didn't as a rule have HiFi separates, things were integrated. Then came separates. Having phono cables became a necessary evil to attache everything together and certainly wasn't seen as a step forward in itself. Now they are a fashion item.

I use non-ROHS 60/40 lead/tin solder, because it melts at a lower temperature than lead-free
