Description
Lightweight Dongle DAC/Amp The KA11 is a compact DAC/amp designed to give your daily listening more clarity and ease. It pairs a CS43131 DAC with a low-noise SGM8262 op-amp and a stable power design that keeps distortion low and detail intact.
0006 percent and the signal-to-noise ratio reaches 125dB. It fits into a pocket, hangs naturally from a phone, and offers enough power for a wide range of headphones without weighing down your routine.
All-day power The KA11 produces 245mW at 16 ohms and 200mW at 32 ohms. That output helps your headphones sound confident at normal listening levels and steady during long sessions.
It gives you room to enjoy your library without pushing the device or your ears too hard. Small design, easy rhythm The KA11 is even smaller than the previous generation, making it simple to bring along.
The short cable stays manageable when you’re on the move. It slips into a pocket, sits lightly against a tablet, or disappears beside a laptop.
Cleaner sound, clearer details The CS43131 DAC works with a high-precision crystal oscillator and a dedicated power supply stage to maintain stable timing and low noise. The circuit layout helps reduce interference, giving quieter passages more space and letting subtle textures come forward naturally.
Stronger cables, softer handling The cable uses high-purity oxygen-free palladium-plated copper wires covered in flexible silicone and braided cloth. It bends easily and handles daily movement without feeling fragile.
The materials support clean signal transmission while staying comfortable to use day after day. Designed for many devices The KA11 works with Android, iOS, Windows, and Mac.
Choose USB-C or Lightning, plug in, and start listening. It supports 384kHz/32bit PCM and DSD256, giving you a portable way to enjoy high-resolution audio anywhere you like to unwind.
App control when you want it On Android, the FiiO Control app allows you to adjust digital filters, RGB indicator lighting, and operating modes. You can shape the sound slightly or choose how the indicator behaves during playback.
The options are there when you want to fine-tune small details. Built with long-term use in mind The KA11 undergoes plug-and-unplug tests, bending tests, weight-bearing checks, salt spray tests, and temperature evaluations.
This gives you a device built to handle commutes, shared desks, travel bags, and everyday handling without feeling delicate. 00038 percent (300 ohms) What’s included KA11 DAC/amp Manual Warranty card
