The Amazon reviews for that cable are wonderful:

A small sampling: (there are many, many more)

    Transmission of music data at rates faster than the
    speed of light seemed convenient, until I realized I
    was hearing the music before I actually wanted to
    play it. Apparently Denon forgot how accustomed most
    of us are to unidirectional time and the general laws
    of physics. 


    I can't recommend this cable enough. I bought a set of 
    four for my home cinema setup, and I haven't regretted
    it at all. [...] When I sit down and listen to the 
    transcendent music they produce, I can feel my pain 
    just drift away. Sometimes I even play a CD, but that's
    not really necessary.

My personal favorites revolve around Tuscan Whole Milk[1] and Uranium Ore / Yellow Cake[2]. Especially the top-rated milk review, and how often the uranium ore shows up when you're searching for yellow cake mix :)

Tuscan whole milk has not been sold for years. Some of the reviews are proof exercising your creative muscles is a win.

The 'Tags Customers Associate with This Product' are also great:

  snake oil(775)
  ripoff(697)
  waste of money(671)
  throwing your money away(613)
  unconscionable(529)
  stupid(502)
  pure garbage(440)
  immoral(433)
  cheat(404)

I think you owe me an hour or so :)

Still can't decide if the ad is for real, but I do recall somewhere in the late 80's an ad for speakers 'designed for CD music only'.

Don't waste my time with that bargain basement junk. If you want professional results, you have to start as you mean to go on.

I highly recommend browsing this site to get an understanding of what quality really means. I have met several people who 'get it' and have installed quality products like this: they have all been very happy with the results. *

I think you guys are just jealous you can't afford any!

I thought my link was bad enough. wow
