Fiio KA11 Portable USB DAC Dongle

The FiiO KA11 proves a proper hi-fi DAC can cost as little as a takeout dinner. This micro dongle replaces the headphone jack your phone lost with something far better: a genuine CS43131 DAC and 200mW of clean amplification in a body that weighs 8.5 grams.

Type and Technology

The KA11 is a micro USB DAC and headphone amplifier pairing a Cirrus Logic CS43131 DAC with an SGM8262 op amp. It decodes PCM up to 384kHz/32bit and DSD256, reaching a signal to noise ratio of 125dB and THD+N as low as 0.0006 percent, numbers that embarrass built in phone and laptop audio.

Sound Character

Clean, smooth and quietly confident, the KA11 has the CS43131 house sound: natural mids, tidy bass and no digital glare. With 245mW into 16 ohms and 200mW into 32 ohms it drives IEMs and efficient headphones with ease and remains hiss free on sensitive sets.

Build and Features

A one piece aluminum alloy body with a fixed cable and gold plated 3.5mm jack keeps it ultra light and durable, with an RGB indicator showing sample rate. It is fully plug and play on Android, iOS (Lightning version), Windows and Mac, drawing minimal battery from the host device.

Best For
