Essrand and Soix,
The NAD M51 sounds great right out of the box. I would say a couple of hundred hours should do it. The NAD benefits greatly from system changes -- power conditioning and cabling in particular. You really need to optimize it to appreciate what it is capable of -- which is a lot more than I ever anticipated. I am still astonished at what it does after owning DACs from $5,000 to $12,000.
