It’s been two years since FiiO launched their K9 PRO ESS and AKM versions, and many of you are probably still rocking those beasts today. But time marches on, and in the meantime, both Asahi Kasei Microdevices (AKM) and ESS Technology have unleashed new flagship DAC chips. Plus, the world of top-of-the-line headphones is populated by power-hungry monsters these days.

The FiiO K19 serves as a comprehensive, all-in-one desktop DAC and headphone amplifier for users seeking impressive audio performance, compatibility with consoles and various sources, and who also possess a diverse collection of headphones.

If you don't see yourself using the EQ functionality, for example, then perhaps the less expensive K7 or K9 series will suffice. But I don't have anything else here which offers everything the FiiO K19 does—except FiiO's own R9 network streamer/DAC/amp which costs even more—to where I acknowledge the K19 will be of interest to many despite the higher price.

Fiio didn't leave anything out in the K19; the DAC has extensive analog and digital connectivity, and you even get HDMI ports and Bluetooth 5.1. The all-new aluminum design with the honeycomb pattern is stunning, and it makes the DAC much more elegant. Delivering up to 8W of power, the K19 can drive any headset on the planet, and it delivers a distinct sound that's wonderfully rich and detailed. You also get a screen that shows playback information, and a built-in DSP engine that lets you tweak the EQ to your heart's content. If you're in need of a high-end DAC, the K19 is the one to get.

Overall, the K19 is a splendidly built all-rounder that can be utilized in many audio setups as a sole DAC, PRE, or DAC & AMP. Its rich I/O offers unmatched flexibility in this price range.
