The Audio Science Review (ASR) approach to reviewing wines.

A brain exercise for those who think all cables sound the same because ASR measured them to be the same:

The terminal connector of a cable cannot be pure copper, because copper cannot hold a shape well enough. It's usually a mix different metals along with copper. This will degrade the signal. 

The actual brain exercise, If you have a cable that degrades the signal, some will degrade less, some will degrade more. Assume you have 1 cable of each, you think they would sound the same?

This is just the terminal connector we're talking about, there are a lot more aspects that haven't come into the picture.

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.

Pure copper makes an excellent spade connector

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.
