Cayin C9 Portable HeadAmp

Cayin C9 Portable HeadAmp

C9 is probably the most sophisticated portable headphone amplifier for both earphones and headphones in the market. Cayin firmly believes that when the amplifier excels in control and equipped with appropriate volume management, there is no such thing as over-powered. Even IEMs will perform at a different level when we have ample power. Unfortunately, from what we observed, most, if not all, high-end headphone amplifiers are designed with full-size headphones in mind, portable amplifiers are mostly DAC/Amp with emphasis on digital audio technologies. Given the rapid development of high-end IEMs in recent years, Cayin believes there is a market for the ultimate portable headphone amplifier that can bring out the best of these high-end IEMs, especially when they are equipped with demanding dynamic, planar magnetic, and/or EST drivers, and yet versatile enough to cover a lot of full-size headphones in portable scenarios.
