idc:Andrew Everard:Cable Lover:It is up to the manufacturers of cables to validate their claims,which they never do except in bland, meaningless statements such as "tighter bass" or "greater soundstage". These words are parrotted by journalists almost verbatim, like an extension of an ad or press release.
Given that the vast majority of cables are made from OFC Copper, please can someone explain what processes are changing from one brand of wire to another to make them sound different? Copper is an element with known physical properties/values. How can this change when electricity is passed along it?
I have long thought that cable manufacturers claims should have a case to answer with the Advertising Standards Authority.
The point is, Cable Hater, that - oh dammit, I really can't be bothered...
I can (for the first time in ages). You single out copper, but there is a lot more to cable manufacturing than that. The connector, how it is plated, the purety of the metals used, stranded or solid core, RFI, EMI, impedance, the sheething used, braided or not, the list goes on.
The role of a cable is to send a signal. The signal is sensitive to the likes of EMI and RFI and other factors. That 'sensitivity' is what audiophiles will hear when one cable is changed to another. Part of our hobby involves listening out for those, often minute differences. Describing the differences is like trying to describe taste and the differences between wines. If you put your mind to it and with practice and even a bit of instruction you can pretty accurately tell the difference between wines and recognise their grapes etc. I say the same is true for cables and hifi equipment in general.
If you have a cable with a cheap primarily plastic connector that is crimped onto low purety copper that is sheethed in the thinnest of plastic and compare it to one with gold plated connectors made the highest of tolerances soldered onto a cable that is copper with a silver mesh surround that is braided to reduce RFI and made with the highest purety of metals, you would expect a difference.
You have to a certain extent, made my point for me.
- At the end of your note you say you would expect a difference. Therefore you believe you hear a difference. It's called psychacoustics!!
- You mention the connector. "If" a cable sounds different, how do you know if it's the connector or wire that makes the difference?
- Same for gold plating
- If the purity of the metals is a factor, then the test results for the cables should be published. If the test results are similar for impedance, capacitance etc. then why would there be a difference between them? It would save the gullible an absolute fortune
- EMI and RFI are external factors and have nothing to do with cable performance unless shielding is present. Again, with today's technology, its effectiveness can be measured very accurately, there's no need for guesswork
- Do you think product designers use equipment to measure performance, or just their ears? And do you think their ears perform flawlessly, or even the same day after day?
