FiiO K15 (silver)

The K15 is a desktop DAC and headphone amplifier for people who want one box on the desk for headphones, streaming and speakers. Two AKM AK4497S DACs decode USB audio up to 768 kHz/32-bit and native DSD512, and the whole path from DAC to headphone output is fully balanced. The headphone amplifier is a discrete class-AB design with ON Semiconductor transistors that delivers up to 3000 mW per channel into 32 Ω from the 4.4 mm or XLR-4 output, enough for demanding full-size headphones, while five gain levels keep sensitive IEMs manageable. Besides USB it takes optical, coaxial, Bluetooth with LDAC, analogue RCA and 4.4 mm signals, streams over Wi-Fi or Ethernet and plays music from a USB drive. XLR and RCA line outputs feed active speakers or a power amplifier, and a 10-band PEQ works on all digital inputs. You control it with the knobs, the 3.93-inch touchscreen, the included remote or the FiiO Control app.
