I work at an electronics retailer where everyone firmly believes that high quality HDMI cables make a huge difference to audio quality. Specifically audio quest HDMI cables. I know that they dont make any difference, and that by their very nature (digital signal) it would not even be possible for any difference to exist between high speed HDMI. The managers even like to setup demos where they switch the HDMI and it sounds better with the more expensive cables... What do people think? How can I show these people that they are ignorant... There is no need to spend $1000+ on a three foot HDMI, yet some people fall for it...
