Headphoneus Supremus
I couldnt pick any differences in background noise floor between dx312, AK sp1k and shanling m9 using my IBasso it07 and beyers xelento (both 16ohm, around 110 sensitivity). I think the amp12EXN is even blacker.I had to use it for AK380 and DX220. For as much as IEMatch helps, I just feel a TOTL DAP needs to be implemented to have the lowest noise floor. So far out of the DAPs I have tried, Cowon P1 is the only DAP that has true pitch black background. You can't tell the player is on between tracks. M6 Pro is probably the close second. I know the player is on, but there is no hiss or hum of any sort. It's kind of like an electric car is idling.
