FiiO K19 Studio-Grade Flagship DAC and Headphone Amplifier - Black

ADI ADSP-21565 with SHARC+ coreA first for FiiO, the K19 utilizes a powerful quad-core FPGA as a high-definition digital signal processing center. The FPGA handles all incoming digital signals, including Bluetooth reception and decoding, USB decoding, coaxial and optical decoding, HDMI/ARC decoding, and DSP digital signal processing. These digital signals are directly transmitted through two sets of I2S channels to the dual ES9039SPRO DACs, ensuring minimal distortion and loss of audio signals in the digital audio processing chain.

Flagship ESS 8-channel ES9039SPRO*2 DACsInside the K19 are two of the new ESS 8-channel ES9039SPRO DAC chips, featuring the fourth generation 32Bit HyperStream architecture and capable of ultra-high dynamic range with ultra-low noise. These DAC chips allow the K19 to output clearer and richer audio with plenty of detail.

8-channel THX AAA 788+ headphone amplifierThe K19 uses a new headphone amplifier design consisting of an 8-channel THX AAA 788+ headphone amp architecture working together in parallel and backed by a high-voltage power supply. The THX amp chips are connected in parallel via 2x2 groups to make up a totally balanced, 4-channel amplification system. The result is enhanced transients, and high-power output up to 8000mW+8000mW with a 32Ω load - allowing the K19 to drive all types of headphones with ease.

Dual ACCUSILICON high-performance oscillatorsThe K19 includes two industry-leading ACCUSILICON AS318-B ultra-low phase noise femtosecond crystal oscillators (45.1584MHz,49.1520MHz), which are 100% pre-screened before being selected for use in the K19. These femtosecond crystal oscillators effectively reduce the impact of phase noise on audio signals and enable accurate audio restoration and different sampling rates - resulting in purer and more stable sound no matter the source sampling rate.

ultra-thin die-cast unibody shock-proof constructionThe K19 features brand new styling, made of a die-cast unibody aluminum alloy body for a totally seamless design. The aluminum alloy body is carefully polished by a multi-axis CNC machine to a quality befitting of a flagship. This aluminum alloy body has reduced thickness, and is also shock-proof. When paired with the included stand, the K19 remains stable!

Separated and Shielded Circuit BoardsThe digital and analogue audio circuits of the K19 lie on separate boards for full isolation and greatly reduced interference. There are metal shields for the DSP board, DAC board, and the THX head-phone amplifier board, as a result of the digital board and module board adopting a compartmentalized aluminum alloy isolation design. These measures all help to minimize crosstalk to ensure signal purity. Tthe honeycomb-mesh aluminum alloy body can also help to further reduce external interference, allowing you to enjoy music in its purest form.
