FiiO K7
FiiO launches the K7 - balanced desktop headphone DAC and amplifier featuring dual AK4493S DACs, dual THX AAA 788+ amp technology, USB/Optical/Coax/RCA inputs, and both 6.3mm single-ended and 4.4mm balanced headphone outputs. Building upon the success of previous FiiO desktop amplifiers, the K7 utilises a truly balanced six-stage audio circuit consisting of: DAC, Low Pass Filter, Volume Control, Buffer Amplifier, Pre-Amplification, and Headphone Out. Throughout this signal path, audio signals from each channel are processed separately by the K7, thereby reducing crosstalk, and ensuring the best sound quality possible.
With its dual THX AAA788+ amplification, the K7 is able to effortlessly power both low and high-impedance headphones. High and low hardware gain levels can be manually selected from the front panel, allowing users to easily adjust the K7 for headphones of various impedances and sensitivities, allowing for a consistent listening experience. The K7 is capable of outputting 560mW into a 300Ω load at 1% distortion; 2000mW into a 32Ω load at 1% distortion.
The FiiO K7 features dual AKM AK4493SEQ DACs - one for each channel of audio - ensuring it delivers a musical, expressive sound, whatever the source. The K7 ensures accurate handling of all digital audio files, at up to 32Bit 384kHz/DSD256, thanks to the dual-clock management of the XMOS XUF208 decoding chip. The indicator light surrounding the volume dial displays different colours dependent upon different audio sampling rates being received: 48kHz and below will display blue; 48kHz or more displays yellow; DSD files display as green.
Powered by an external 12V switching power supply, the K7 features an internal power design architecture consisting of multiple independent stages. The voltage of each of these stages is regulated using low-noise Low-dropout Regulators (LDOs). In addition, intelligent DC protection systems guard against overheating and overload; ensuring the K7 delivers a consistent high-quality listening experience. The FiiO K7 is available now, priced at £189/$199. Info and photos by FiiO via Starscream Communications.
