I even showed him this one post on I believe a Sony website where an electrical engineer in broadcast explain the concept of Digital Audio/Video transmission....he still insisted on buying overpriced cables because of his "employee discount"... I don't care if you do get a discount! Why spend any money on overpriced cables? I can send 8ch's of 96khz Uncompressed PCM over HDMI from my MacBook Pro....and it will go over any HDMI cable with ease and sound the same vs some other $100 cable :O
Well as a matter of how science of digital audio works, that is not the case. It simply is not just 1s and 0s. Here is an article I wrote for Widescreen Review magazine that explains why: http://www.madronadigital.com/Library/DigitalAudioJitter.html
That's not to say that such cables automatically make an audible difference. I personally don't shop for audio fidelity when it comes to HDMI cables (there are far bigger fish as far as the darn thing working at all!). But when we are talking about the science, we better be accurate about it. And saying it is all the same simply does not reflect how the technology works. And oh, one of my previous jobs was VP of engineering at a company that build broadcast video equipment. While I had some of the best video engineers in the world there, I would not expect any of them to know how consumer audio works. It is a different world than what happens in the pro world and at any rate, transmission and full reproduction to analog stage are two different animals (and source of confusion among even professional engineers). Again, all explained in the article.
Net, net, what your DJ friend said may have very well been baloney but not for the reason stated
