funny
A couple months ago I was curious so I asked the "new" ARC by email - how long does it take to burn in your DAC ? ARC Customer Service responded back "look in the manual". Nothing in the manual about burning in.
Make what you want with their comments.
Prior to this, quite a while ago when I first got the DAC, and was still able to communicate directly with staff at ARC - I was given an hours estimate.
Cheers
