FYI Just got this from Denafrips
Good day to you.
All Denafrips products will undergo the mandatory 100hr burn-in in the factory.
Due to the fact that DENAFRIPS components benefit from long burn-in, hence we will recommend burn-in for another 300+hrs to achieve optimum sound quality.
You'd expect the sound to open up, great details & resolution, and better flow of music.
Burn in is a big controversial topic in the audiophile community.
We believe that burn-in will be more effective with soundtrack playback. The speaker can be turned off while keeping the DAC continues to burn in with music.
There is no hard rule to follow, but it is recommended continuous burn-in if it is connected with a streamer/computer playback, whilst for CDT it is advisable to burn-in as you used it.
Do give it some time to break in to sound at its best
Many thanks.
Yours sincerely,
Vincent Ong
