Je ne résiste pas à l’envie de partager de lien (assez vieux) sur la page Amazon des commentaires pour le câble audio Denon à 500$ (non ce n’est pas une erreur de frappe). A un tel prix, pas étonnant que les internautes se lâchent sur les reviews… A vous de juger. Voici quelques morceaux choisis:

A caution to people buying these: if you do not follow the “directional markings” on the cables, your music will play backwards. Please check that before mentioning it in your reviews.

I was disappointed. I consider myself an audiophile – I regularly spend over $1000 on cables to get the ultimate sound. I keep my music-listening room in a Faraday cage to prevent any interference that could alter my music-listening experience. Sending any signal down ordinary copper can degrade the signal considerably. While ordinary listeners might not notice, to somebody with even a rudimentary knowledge of sound, the artifacts are glaring. Denon should have used silver wiring (hermetically sealed inside the rubber sheath to prevent any tarnishing, of course), which has a significantly higher conductivity than copper. Furthermore, Denon needs to treat the wires they use in the cable with a polarity inductor to ensure minimal phase variance.

Needless to say, I returned the cable and wrote an angry letter to the so-called engineers at Denon.

After I took delivery of my $500 Denon AKDL1 Cat-5 uber-cable, Al Gore was mysteriously drawn to my home, where he pronounced that Global Warming had been suspended in my vicinity.
Yes, I had perfect weather: no flooding, no tornadoes, the exact amount of rain necessary, and he pronounced sea levels exactly right and that they were not going to rise within five miles of my house.
Additionally, my cars began achieving 200 mpg and I didn’t even need gasoline. I was able to put three grams of cat litter into the tank and drive forever.
What’s more, the atmosphere inside my home became 93% oxygen and virtually no carbon dioxide. In fact, I now exhale oxygen.
One heck of a cable.
Didn’t notice any improvement in audio quality though.
The $800 Apple iCable is clearly superior.

I thought I should mention that while this amazing cable is supposedly 1.5 meters long, I find this quite misleading. When I opened it at first glance 1.5 meters seems accurate. It certainly didn’t feel much longer than 4-5 feet in my hands, but I have since used it to span much greater distances.

So far I have successfully used this cable to share my internet connection with my parents’ house across town, create a wired network connection to a nuclear submarine in the Pacific and, most recently, share files with astronauts on the International Space Station in orbit around the Earth.

I’m not sure how any of this is possible. I suspect it is made of supermolocules, but this cannot be determined with any certainty.

I am currently planning on buying another cable and sending one end on a rocket to Alpha Centari in hopes of connecting my network to any alien civilizations there. I expect the faster-than-light communication features of this Denon cable will be a great asset in growing our knowledge through contact with other intelligent species.

For $500 I would have expected these cables to be worn in. They aren’t. The procedure for pre use wear in of digital cables is significantly different to analog cables. They should be worn in for a period of 24 hours in each direction. Use a unidirectional protocol! _Never_ use TCP for wearing in digital cables, as TCP uses return packets for acknowledging, causing interference in the uplink channel being pre worn. Use UDP or ICMP (no ping) for wearing. Preferable use a payload of 64Kb with a datapacket consisting of consecutive 1′s and 0′s to settle the electrons. After 24 hours, reverse the cable and repeat. Always make sure that the cable is connected to a sender and a receiver, as Layer 2 will prevent data transmission if there is no positive ARP response from the receiver.

This process is quite delicate and difficult, and I would have expected it to be performed by the manufacturer for this pricetag.

Et il y en a des pages… A lire dans un moment de déprime !
