Possibly but when you have spent much money on nice why not take the time to do it properly. And for every 100 people on hi fi or speaker forums say they don't need breaking in 100 people say they do so it's up to you who you chose to believe.
Sums it up pretty well. The reason that you're told to give it 30 hours or 100 hours is to allow your ears to get used to a totally different sound than you're used to, rather than just taking the whole lot back straight away and saying it's rubbish. It's a manufacturer customer relations ploy, not a technical/scientific one, because people are fickle things who get used to hearing stuff sound a particular way.
