Even more compact but still powerful Compared to the previous generation product, the KA11 is even more compact – making it even more portable and easier to carry around and use. Thoughtful design and specially chosen parts allow the KA11 to have a large power output despite its compact size, making for a solid foundation behind its great sound. 245mW@16Ω 200mW@32Ω Specially-designed HiFi circuit A high-performance DAC and op-amp, a high-precision crystal oscillator, as well as an independent power supply are all combined in a specially-designed audio circuit that allows the KA11 to effortlessly produce great sound. The high-quality parts are all carefully laid out on an immersion gold finish circuit board, allowing the KA11 to have great measurements. As a result, the KA11 is Hi-Res Audio certified – a testament to its excellent sound. High-quality cable and eye-catching design The cable is made of high-purity oxygen-free palladium-plated copper wires, which allow for low impedance, quick transmission of signals, and resist external interference. The copper wires are covered by a layer of flexible silicone and braided cloth, making for a soft yet durable cable. The aluminium-magnesium alloy body is tough, yet also looks elegant with its perfectly placed curves and its inlaid designs. It is a device that will surely catch your eye. Compatible with many devices With the KA11 being available with both USB Type-C or Lightning connectors, you can freely connect it to Android/iOS phones and tablets or to Windows and Mac computers – letting you freely listen to music at your convenience.
