In a previous post, sfrounds1 reports unhappiness with his new DS sr. with the Snowmass upgrade. The vast majority of responders cite insufficient break-in time as the cause though he has 60 hours. Some responders indicate as much as 500 or even 1000 hours are required.
If such lengthy break-in time is necessary, should the component ship with a manual that cautions the owner that a lengthy break-in time is needed before the DAC will live up to its potential? Does the engineering team that designed the DAC acknowledge so extensive a break-in time is necessary?
