The FiiO K17
When you unbox the FiiO K17, you’re met with a blast from the past. Its brushed aluminum finish and energetic VU meters give it the aesthetic of a high-end audio relic from the late 70s. But don’t be fooled by its retro exterior—this is a powerful, next-gen desktop decoding headphone amplifier made for today’s discerning audiophile. With a price tag of $899, the K17 is the perfect balance between great performance and a good investment, especially if you want to improve your own sound experience.
Not just enthusiasts, but audiophiles
This unit’s specs sound like a dream for anyone who loves music. The K17 can put out up to 4000mW+4000mW of power in balanced mode, which is almost twice as much as the well-known K9 Pro ESS. Dual AKM flagship DACs are paired with discrete transistor amplification to ensure signal purity and detail. Add to that a 31-band, high-precision, lossless PEQ (Parametric Equalizer) and you get a setup designed for ears that catch every nuance.
Tactile Satisfaction Meets Technological Precision
You don’t just use the K17—you interact with it. With a solid 2.75-kilogram metal chassis, it has a physical presence that demands attention. It’s the kind of equipment that makes you rearrange your desk like you’re making room for a sacred object. Its physical switches and responsive touchscreen offer a blend of analog satisfaction and digital functionality. Twisting its volume knob delivers the kind of tactile pleasure that flat touchscreen controls simply can’t replicate.
Audio Testing That Backs the Hype
Reviewers haven’t held back their praise. Guy Lerner from The Headphone List compared it to the far more expensive Astell & Kern ACRO CA1000T. After weeks of testing the K17 with various headphones, sources, and genres, the verdict was clear: this amp punches far above its weight. Audiophiles have noted how effortlessly it handles high-resolution audio formats and brings out details that often get lost in standard setups. If you’re always chasing the best new gadgets in audio, the K17 won’t disappoint.
More Than Just a Pretty Face
Yes, it looks stunning. But this amp’s appeal goes far deeper. For many users, the K17 rekindles a love for music as an experience—not just background noise. It brings back the era when audio setups were events in themselves. If you’re someone who grew up streaming compressed MP3s, the K17 offers a wake-up call to what true fidelity sounds like.
