Oh Simon!!! What have you started!!???:duck: Just to add my penny worth in. I think the dealer was very brave to do a mains cable comparison. I personally wouldn't feel confident to take on that demonstration during a show, There is far too much ambient noise to make any kind of proper judgement. There is a lot of fuss over nothing and people getting far to upset over things. I wasn't at the show and i don't know what happened but I wouldn't heckle a demonstration especially when the exhibitor has just paid a sum with at least 3 zeros in it. By all means write up about it or have a discussion with the exhibitor but don't undermine him during the demo good or not. I must say I enjoyed the write up and Simon always say it like it is and will pick up on things.
