Is a successful performance more important to the audience than an authentic one?

With this I would think that the answer lies in what kind of taste the audience as a whole has for music. I would think that the need for authenticity in a performance is trumped by that of the success of the performance. Whether or not a performance is authentic, if it was not successful, the audience will not like it as much as they would if it had been successful. So the conclusion would be that a successful performance is more important to the audience than being authentic.
