FiiO is positioning the K15 as featuring “trickledown technology” from its higher-end K17 model, claiming to achieve pricing at half that of comparable rivals.
The company claims that the new K15 delivers an organic, immersive sound signature, while maintaining ultra-low distortion and wide dynamic range. Whether that translates to genuinely premium performance at this price point, remains to be heard.
At the heart of the amplification stage sits a discrete Class A/B circuit capable of delivering up to 3000mW per channel through its balanced output. That should be enough grunt to drive both sensitive in-ear headphones and high-impedance over-ear headphones.
The fully balanced signal path extends from the DAC stage right through to amplification, with FiiO choosing a tri-board design that separates digital, analogue and power supply sections across different PCBs. This approach should, in theory, reduce crosstalk and electrical interference for cleaner sound reproduction
