Features 5
- The FiiO K17 is the first to feature a discrete amplifier circuit, utilizing an OP + transistor current-driving headphone amplifier design. It is equipped with the On Semiconductor MJE243G/253G classic complementary pair, enabling high-current, low-impedance output. The balanced output power reaches up to 4000mW+4000mW, effortlessly driving both large headphones and in-ear monitors. The sound is smooth, natural, and melodious, delivering a pleasant listening experience.
- The device uses the AKM flagship DAC chip combination AK4191 + AK4499EX*2, with each AK4499EX handling one channel. This is paired with an 8-channel to 4-channel LPF design to reduce common-mode interference, resulting in better separation and dynamics. Additionally, it features a fully separated digital/analog structure based on a new design technology, incorporating the newly developed "DWA ROUTING technology" to further purify the background and enhance resolution.
- The FiiO K17 is equipped with the professional DSP chip M21586Q and the high-performance ADC ES9821Q, complemented by a custom-designed ultra-low phase noise femtosecond crystal oscillator. It offers a 31-band professional-grade high-precision lossless PEQ adjustment function across all input modes. This allows for simulation or correction of headphone frequency response curves.
- The FiiO K17 supports multiple input options, including single-ended line input, balanced line input, USB decoding, Bluetooth decoding, optical decoding, and coaxial decoding. The USB decoding uses the XMOS 16-core chip XU316, supporting 768kHz/32bit, DSD512, and full MQA decoding. Bluetooth decoding is powered by the Qualcomm QCC5125 chip, featuring Bluetooth 5.1 and supporting aptX HD, aptX Adaptive, LDAC, and other codecs. For streaming, it supports Roon Ready and AirPlay, giving you access to a vast array of streaming sources. Local playback is supported via external USB drives and portable hard drives, allowing you to enjoy your precious collection of audio files.
- The K17 features a custom-designed 3.93-inch LCD screen, allowing for quick switching between various settings and functions via touch controls. It also includes five independent control knobs, supporting one-button standby, and enabling fast adjustments for volume, gain, output, and more. The device comes with an infrared remote control for convenient long-distance operation, allowing you to easily switch between work modes, select EQ settings, and adjust volume.

Left Channel Pops - UPDATED REVIEW
Color: Black
Everything about this Amp was great, except occasionally there was a slight pop only in the left 4.4 channel when switching songs or changing inputs. At first I thought it was my headphone, so I returned it. I was using a balanced connection with that one. I wasn't using balanced with the others, so no real issue. I didn't realize it was the unit till I got another balanced headphone and heard the same noise. My other Schiit Dac doesn't have that issue, but it doesn't have as good tonality or noise floor as the Fiio. I'm going to try another k17 and hope it doesn't have that issue. ***Update*** I returned the above unit and re-ordered a replacement. ZERO issues with that pop sound with the new unit. LOVE this Dac/Amp now, the sound quality is amazing. It is a little tricky to get the PEQ to work on a Mac Laptop, but technical support was pretty good and responsive. Keeping it at 3 stars because of the first issue and the lack of PEQ ease install.

Superb DAC AMP combo
Color: Black
Superb all in one unit. Great sound, retro looks, drives all my headphones (including my very insensitive planar magnetics) with more than enough headroom. Very worthy of high praise

Mi mejor DAC - Amplificador de auriculares.
Color: Black
Fiio siempre a sido un amplificador de auriculares que me gusta como reproduce la música, tienen una excelente escena sonora y mucho detalle, sin ser analítico. Con el Fiio k17, tengo la mejor opción por el precio, para disfrutar de música y con múltiples opciones de ganancia, de visualización, de fuentes de entrada y más....

K17 and Roon issues
Color: Black
Update: My K17 got into serious trouble today. Suddenly, it failed to grab the IP address (it's using an Ethernet cable). It means the streaming did not work at all. After the last firmware upgrade, the streaming has been working fine for two days. Now, it's just getting stuck no matter how many times I reboot it. Update: I can claim the last K17 firmware updates, Main controller firmware V183 and MCU firmware V87, fixed the issues I encountered with Roon earlier. I got my K17 from Amazon yesterday, hooked it up, and successfully updated the firmware. I connected it to my home network via the Ethernet cable. Roon Sever could find it and included it in one of my Roon Ready devices (I have WiiM Ultra and Node 2i Roon Ready devices too). I tried to play music via Roon, and it started well. No complaints! However, after I stopped listening to Roon's music and tried to play more songs afterwards (let's say 2 or 3 minutes later), the K17 disappeared from my home network automatically. It had to reboot K17 to get it back to normal. Did it disconnect the network automatically after I stopped Roon's music playing? It happened repeatedly, and it was so annoying. This kind of issue never happens with the WiiM Ultra and Node 2i. I can stop & play Roon's music via WiiM Ultra or Node 2i without problems all day. I guess it has something related to the K17 firmware (I got and installed the latest one from FiiO though). Hope the company can fix this issue ASAP!
