Description
The FiiO KA11 is a pocket-sized DAC and headphone amplifier for audiophiles seeking high-resolution audio. Built around the Cirrus Logic CS43131 DAC and SGM8262 op-amp, it handles PCM up to 384kHz/32-bit and DSD256 with Hi-Res Audio certification. At 8.5 grams and 44.5mm, it stays unobtrusive whether clipped to your phone or in a pocket.
It delivers 245mW into 16Ω and 200mW into 32Ω — enough to drive most IEMs and many headphones without a separate amplifier. The Sunrise Silver aluminum-magnesium alloy housing with blue accents feels premium, while high-purity copper conductors with palladium plating and a silicone and braided fabric outer sheath endure thousands of connections. The immersion gold-finished circuit board keeps distortion below 0.0006% and signal-to-noise ratio above 125dB.
It connects via USB-C to Android, iOS, Windows, and Mac with plug-and-play simplicity. The RGB LED indicator shows your audio format in real time — blue for standard PCM, yellow for high-res, green for DSD. Android users can access the FiiO Control app to customize digital filters, adjust RGB lighting, and enable UAC 1.0 mode for low-latency gaming on Switch and PS5. Reviewers praise its warm, musical character and impressive power output for the price.
