FiiO’s Line Of DACs Just Keeps Growing In Volume
We’ve seen FiiO before, including their K7 back in January, and they are back with a new ~$500 DAC called the K9. The FiiO K9 is not simply a headphone amp, although it can handle both in ear monitors and headsets with an impedance of up to 32 ohms. It has inputs similar to the K9 Pro ESS. including XLR as well as USB, RCA, balanced 4.4 mm, optical, Coax and even Bluetooth. The outputs are almost as impressive and include XLR, 4.4 mm balanced and a single-ended 1/4″, which should cover just about any scenario you might come up with.
Inside the FiiO K9 you will find SS Sabre ES9068AS 32-bit 2-channel DACs, not quite as high end as the K9 Pro ESS but certainly capable of handling most of what you might throw at it. Additionally two Texas Instruments OPA1612 low pass filters and two THX AAA 788+ linear amplifiers assist the DACs to ensure you have control over your audio outputs. TechPowerUp have a lot of good things to say about the FiiO K9 in their review including Roon integration, though they would like to see the app include proper parametric EQ.
