“Your burn in cd seems to work wonders, have had it on repeat all day at very low volume to burn in my new simaudio dac. I got the Moon Neo 280D dac from Simaudio, their products are know for slow burn in. Just after a workday of track 2 on repeat it starts to sound more like (burnt in demo ex ofc) it did in the store, softer, more “analog”, more comfortable.”
