How will most people judge a system? Lets suppose there are 5 DJs in a room/Ballroom/EventHall, each with his/her own system. There is an audience that has to rate them for overall performance. What do you think will be the determining factor? There are four options listed. I have left out weight/ease of transport because if I was a judge I would not care about that and I don't think others would either. (That is a DJ only issue and not a selling point)
