I do not need Fiio engineers deciding what is acceptable for equipment I buy.
You state the obvious, then state an opinion which is not shared by some. In car audio this would be crippling info but in headgear it's supposed to be a plus? That engineers decided acceptable? Using what genre? What cans? What exactly was determined to be the threshold before audio degradation reached an un-acceptable level? At what dB and at what input?
There are several ways to eq. I would never buy the X3 because it's band eq and the spec didn't tell me where the bass band was centered or what the Q was.
How about FiiO add a section to the homepage describing how the FiiO engineers have worked hard to ensure their ear and equipment safety. Why not?
I'll tell you why cuz folks do not want folks they have never met deciding for them what is acceptable. You pay and you pay again if your a moron. I was unaware of the almost useless nature of the eq until I bought it as folks here were not talking much or suggesting possible firmware updates with a little more headroom.
I got it to work with trial an error and an amp that takes over which I captured in a vid. You can see the dap pass and defer to the amp. The volume is almost useless on the dap with eq engaged.
I have been pimping and pumping the e12 in my thread and many many folks have bought that little brick of awesome and the X5 is nice but folks ...man....acceptable?
Really?
