why do people feel the need to buy expensive cable


I have tried expensive cables and one's moderately priced. I would say there were some differences but I can't actually say the expensive cables were better. IMHO I believe a lot of people buy expensive cables because they don't actual trust their ears and are afraid of making a mistake. They figure the expensive cables are better for the fact they cost more. If you have a difference of opinion or share the same thoughts, I would like to hear about it.

And to think the UK used to be such a bastion of high end audio. What a shame.
Bottom line cables make a difference. If you can’t hear the difference don’t buy them.  If you can’t hear the difference then you shouldn’t try to comment because your hearing is probably off some or a lot!

The BBB comparison is not quite fair as the ASA is a statutory body (ie a government agency), more like the FDA ruling on a drug claim
Sorry, but ASA is not a "statutory body" or government agency at all, but a self-regulatory agency very much like the BBB. According to its own website, it was first  established  by the advertising industry as the Committee of Advertising Practice, which then created the ASA in 1962.
Thanks for the information supporting my original contention that there was no court case. Besides, the whole thing was resolved in favor of the cable company. So willemj’s contention of a court case was a perfect example of fake news. Also known as a nothing burger. 🍔
