I've noticed engineers as they move into digital equipment the tendency to want to "push" the signal towards 0 as they are accustomed too in the analog world. What these engineers don't realize is that it is completely unnecessary and actually less desirable in the digital domain. Another shortcoming is engineers not understanding that meters come in different varieties. 0dbVu does not equal 0dbfs. Understanding these differences is important for any engineer to effectively use their equipment. For more information on this I recommend the following article.
