{"type":"firestarter.listing","listing":{"id":"lst_axtfkR13","product_name":"FiiO KA15 DAC and Headphone Amplifier (Apos Certified)","category":"Headphone DAC/Amp","description":"FiiO KA15 Portable USB DAC/AMP\nThe FiiO KA15 is a pocket-sized DAC/amp that punches way above its weight, delivering desktop-class performance from a device small enough to disappear into your pocket. Built around dual Cirrus Logic CS43198 DAC chips and a dual op-amp output stage, it offers up to 560mW per channel in desktop mode, giving it the muscle to drive full-sized, high-impedance headphones while still playing nicely with sensitive IEMs. \nPrecision Tuning with PEQ\nThe KA15 includes a ten-band high-precision lossless parametric EQ. With FiiO’s DSP and advanced algorithms, you can fine-tune frequencies smoothly through the companion app or web interface. Curves can be saved, shared, or imported, allowing you to adapt sound profiles to different headphones or preferences.\nStrong Output with Desktop Mode\nDespite its small size, the KA15 can deliver 560mW per channel in desktop mode. This ensures it has enough power to drive demanding headphones while maintaining clarity and dynamics.\nDual DAC Architecture\nBuilt with two Cirrus Logic CS43198 DAC chips and dual op-amps, the KA15 achieves low distortion and a balanced sound signature. This architecture ensures both detail retrieval and smooth musicality.\nIntelligent Power Management\nThe KA15 monitors current and voltage in real-time, adjusting power consumption intelligently. This allows efficient use with smartphones and computers while switching to higher power output when needed.\nProduct Highlights\n\nTen-band high-precision lossless PEQ with app and web
