How to improve your digital audio?

Have an extra $2194 and would prefer to give it to greedy liars instead of worthy charities?  Then buy yourself one of these 10-foot Ethernet cables.  According to the description:

Even finest high-purity metals have imperfections and grain structure, which due to the direction of casting and drawing become non-symmetrical structures without the conductor. In ways which are not fully understood, both analog and digital audio performance is significantly affected by these non-linearities.

Oh, I fully understand it.  Gullible people can be talked into anything.
