Pure copper makes an excellent spade connector
The Audio Science Review (ASR) approach to reviewing wines.
Imagine doing a wine review as follows - samples of wines are assessed by a reviewer who measures multiple variables including light transmission, specific gravity, residual sugar, salinity, boiling point etc. These tests are repeated while playing test tones through the samples at different frequencies.
The results are compiled and the winner selected based on those measurements and the reviewer concludes that the other wines can't possibly be as good based on their measured results.
At no point does the reviewer assess the bouquet of the wine nor taste it. He relies on the science of measured results and not the decidedly unscientific subjective experience of smell and taste.
That is the ASR approach to audio - drinking Kool Aid, not wine.

https://www.youtube.com/watch?v=GMjBUvEHVdc Here’s another video of Erin with even more amplifiers. A traditional Mcintosh with a house-sound and piss-poor measurement, vs a pair of Mono class D with "better" measurements with a focus on pure neutrality. What’s the listening result? He cannot hear a difference. Only past 95 db where he starts to feel the Mctinosh has an edge in power. Makes you wonder why even bother with Sinads and THD in the first place. Between you and me, I’m willing to bet Amir can’t tell the difference between a tweeter and a bird. |
@devinplombier "Pure copper makes an excellent spade connector" A pure copper spade will have uneven bumps resulting in poor connection. |
@samureyex I stand corrected |
No, I am just suggesting that your assertion that speed is faster in silver is wrong. Capacitance and inductance are primarily characteristics of the cable construction. If we narrow the debate to speaker cables (that is high current, low frequency domain), in my opinion there should be an audible difference between cables if they differ in say resistance (as copper and silver cables of the same diameter would). The primary reason is that loudspeaker impedances vary greatly with frequency, especially in cross-over regions. The impedance of the speaker and the resistance of the wire are in series. Changing the wire resistance means relatively more or less power is delivered to the speaker over different parts of the audible spectrum, changing the tonal balance for those with golden ears.
The malleability of pure copper means that those ’uneven’ bumps present on any surface get squished into the holes, providing more contact area especially in spade configuration. The ideal connector has no discontinuities and no contamination - I am thinking of friction or pressure welds. Of course it is no good if it breaks! |
