【Main differences on the electronic part】
1. Different DAC: the K9 Pro ESS uses dual ES9038PRO (the best flagship DAC in the ESS family), while the K9 Pro uses the best AMK AK4499, which has been discontinued for 2 years due to the fire that happened to AKM.
2. Slight difference on the internal circuit: due to needs on adjusting the power supply, indicators and sound properties, we have made some slight adjustments on part of the electric circuits (But the key parts are still the same, as excellent as the former ones).
3. Slight improvements on the output power, distortion and SNR compared to the K9 Pro.
