FiiO K7 Desktop DAC and Headphone Amp with Bluetooth Overview
The FiiO K7 Desktop DAC and Headphone Amplifier is tailored for audiophiles and features a six-stage audio circuit with balanced analogue and digital sections, significantly reducing crosstalk and elevating the purity of music playback. Equipped with the same THX AAA 788+ amplifiers found in the K9 Pro, the K7 delivers an impressive 560mW into a 300Ohm load and 2000mW into a 32Ohm load, ensuring it can power both low and high-impedance headphones with exceptional clarity and emotional depth. Each channel is powered by an AK4493SEQ DAC, offering a sound that is both rich and delicate.
Moreover, the K7's decoding capabilities are supported by the XMOS XUF208 decoder chip, making it compatible with a wide range of audio formats. The inclusion of RGB indicator lights adds a visual flair to your desktop while comprehensively keeping you informed on your music's resolution. With its high and low hardware gain levels, finding the perfect volume for any headphone type is effortless, and perfect for serious music enthusiasts.
