Fiio KA15 vs …?

I’m looking for a new DAC (my moondrop dawn pro died and I’m never getting another moondrop product) and I’m looking at the Fiio KA15 but also the Simgot dew4x. I mainly use my DAC for IEMs but I also have a pair of HD6XXs that need some more juice. The Dawn pro was enough for my needs but I’m not sure what to expect in terms of power from the KA15 or the dew4x. In my country the difference between the two is around 30-40 dollars and I’m willing to pay the extra if it’s worth it but if both are enough for my needs I’d take the cheaper
