A fresh pair of ears can be the difference between a good-sounding CD and a great one. A real advantage of Mastering is that an unbiased sound professional has the opportunity to evaluate your Master and determine how to get the most out of your production. After you've spent weeks or even months in a recording studio listening to your CD over and over again, a fresh pair of ears can put the project into perspective for you and let you know whether or not your CD will benefit from post production. After all, you only have one chance to make your music sound its best.
