I just received my DAC-9. What is sufficient run in/burn in time? I've had the cd player on repeat and the DAC powered on (amps off) for about 48 hrs so far. Won't be able to listen to it until Thursday. Listened for just a few minutes this morning but the dac and amps (tube amps) were both just turned on as I had them both off all night. Curious what if any changes will occur over the next few days if I leave the cd player repeating and the dac powered on for the next few days...
