ieales, I am guessing no easy answer to how long does burn in nirvana takes. In my quest to upgrade my NAD stuff, I took all three units in and had my guy replace all the caps, wires and whatever else he could to upgrade the units. $850 in parts. I was deeply depressed when I got it all back. All the warmth and richness was gone. It sounded horrid. I ran it 24/7 for a few weeks with all sorts of music plus the Effacious CD. Finally, it started to sound musical again... and then better than before.
