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.

Silver is 6% faster than copper, you think that doesn’t change the sound?

Really? Silver may have 6% lower resistance than copper, when compared by volume, but do you really think that makes the signals it conducts travel 6% faster?

Electrical signals travel at close to the speed of light. Copper is entirely capable of transmitting Giga-Hertz digital signals, for example high speed Ethernet, using thin, unshielded, twisted wire pairs.

Maybe you think that halving the resistance of a copper wire (by doubling its cross-section) doubles the speeds of the signals it carries? No, it doubles the current it can carry for the same voltage drop.

Pure copper, because of its softness or malleability, makes an excellent connector but does tarnish over time.

@richardbrand Are you telling me silver and copper sound the same? They have different electrical properties, different capacitance and inductance, so the question is, do you think they both sound the same?

Also pure copper is far from an "excellent connector". For the same reason you stated, its softness and malleability, the opposite of what a good connector represent.

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.
