FiiO K9 Pro ESS OPEN BOX

FiiO K9 Pro ESS OPEN BOX unit, very good condition, complete, 1 year warranty. 

FiiO has designed the new K9 Pro using two high-performance ES9038 Pro DAC chips from Sabre Technologies. The ES9038 Pro is a flagship-grade 8-channel DAC that is capable of providing ground-breaking performance in decoding high-resolution audio signals. 

With the help of this new DAC chipset, the K9 Pro ESS achieves ultra-low THD+N(<0.00025%) and high SNR(>129dB) ratings ensuring a super-clean performance.

Consisting of two high-performance THX AAA 78+ amplifier chips, the K9 Pro ESS provides a clean and powerful output signal. It brings the best out of our connected headphones/in-ear monitors with its clean output power signal. There is no noticeable background noise or distortion even with highly-sensitive headphones and in-ear monitors.

FiiO has designed the new K9 Pro ESS with a fully differential circuit in which the signal goes through the DAC, Volume, and AMP sections in a fully balanced manner. It also has a six-stage audio circuitry. The analog and digital circuits have separated designs with partitions for clean performance.

FiiO has featured dual independent Femtosecond clocks to provide a precise clock management system. It makes it easier to handle different sources while maintaining maximum quality performance.
