How much does it take to produce the "Berliner" sound?

Everyone who has played in an orchestra would have a love-hate relationship with the conductor. On the one hand, it is the conductor who puts the orchestra together. On the other hand, the conductor, as the only speaker in a rehearsal, can also give the orchestra such a hard time...
