Over the years we have launched the K5 Pro K7 K9 and K9 Pro - all amplifiers at different
price points. The K series of amplifiers have sold well all over the world. As user needs have
changed and the demand for head-fi has increased thanks to continuous research and progress
we have gained a new understanding of entry-level amplifiers. The K11 includes many
connectivity options high power output and a slim design. The beautiful display is a testament
to its skills as your 'desktop head-fi' companion. - Fiio.
