I was responding to ONE single point of yours, that you suggest FiiO to include S/PDIF input in its future DAP, which I think is an non-essential function, based on the belief that resource should be better used to improve the basic function instead of adding more. I'll rather have a DAP that is just-great-as-a-DAP instead of a "semi-DAP + DAC + whatever everyone wants" audio frankenstein. You can't argue that every extra feature will cost something - either it is the PCB size, the parts cost, battery life, complex firmware coding, etc. The problem is, where do we stop adding features? Someones wants S/PDID input here, another wants native DXD support there, then another wants USB Host for USB DAC, then maybe someone want Android with Playstore access that allows for audio apps... All great and valid idea to someone, but eventually it is not a DAP anymore. My opinion is, let a DAP be a DAP first. In fact, let it be a great DAP first, everything else can wait.
I don't know who and what you are not happy about before my previous comment (which I do not read, as I don't care about them), but obviously it is you who are over-thinking a simple response to something more sinister in nature.
