ES9038Q2M in Khadas tone1 is definitely responsible for the hump,output stage has little to do

Hmm, have you seen this thread already...?

How to Fix ESS Hump on SGD1 and LA-QXD1

Finally on this sunny Sunday, I scheduled a time to share the ESS hump repair solution. The following method only verifies the two SONCOZ DACs SGD1 and LA-QXD1, both of them using ES9038Q2M DAC chips, and the others are only referrals. To save you time, first put forward the method and...

For the ES9038Q2M DAC chip, adjusting the combination of resistance and capacitance values of its IV converter and LPF circuit can fix the hump problem，and it belongs to the hardware repair scheme.

I've been following these threads for a long time more or less everywhere, both here and on diyaudio and so on, the ESS hump has so far been connected more or less only with ESS DACs and some manufacturers and technicians have gradually learned to deal with it thanks to their own research, however this is new to the AKM brand. In general, I see not 100% of the chip manufacturers' work in the development of debugging and supporting the implementation of final device manufacturers as a considerable problem.
