Hi to all!
The first player I got in January and it was burned-in to about 700 hours. I can say that the sound has changed so drastically, it literally is like heaven and earth compared to the sound out of the box. But unfortunately, the player was from a bad batch (for many reasons at once) and one day it is turned off and is no longer power on and even deteсеed by the computer for reflashing.
The second player on the replacement I received 2 days ago and I can confirm that out of the box it sounds so dirty and hard that you did not want to listen it, knowing how this baby can do to play. I could not understand why such a striking difference with the burn-in of this player, as with other electronics it is, but not significantly, and realized that in the DX200 has many as 16 ESS cores and a lot of other duplicated components, which are burned so much affect the sound.
So burn-in is not a placebo my friend.
Have a good time and let you are pleased with your purchase
