The Lightning cable is captive, 65.5 mm long, and links the dongle to your Apple devices with no adapter. The KA11 measures 44.5 x 9.7 x 10.5 mm and weighs 8.5 grams, in an aluminium-magnesium alloy shell. The two-tone black and silver design gives it a tidy look.
The converter is a CS43131, backed by an SGM8262 operational amplifier. The pair accepts up to 384 kHz at 32-bit as well as DSD256, and the KA11 is Hi-Res Audio certified. The circuit board is immersion gold-plated and the conductors are palladium-plated oxygen-free copper.
The 3.5 mm headphone socket takes your earphones or headphones. Into 16 ohms it delivers 245 mW per channel; 200 mW into 32 ohms and 22 mW into 300 ohms. The stated signal-to-noise ratio reaches 125 dB into 32 ohms, for a noise floor below 1.7 microvolts, an output impedance under 0.7 ohm and distortion under 0.0006%.
