FiiO KA1 Review
In other words, the KA1 is completely flat across the audible frequency spectrum therefore other specifications will matter more and more so it affects the overall sound signature.
The KA1 uses an ESS DAC chip which on average sounds rather warm but this dongle presents sound in an almost antiseptic way in which nothing is emphasized and is neither warm sounding nor bright. If I would put it on a legal scale it would tilt one degree to the warm side but that’s it.
There seems to be an absence of coloration overall and this dongle seems to aim for neutrality. Clarity is rather high far as the distinction between different elements within recordings and timbre seems to be unaltered.
The noise floor is kept very low but I think it has more to do with the mute feature within the chip that shuts down the audio output if no audio is present. This gives the listener a totally silent background between tracks.
