FiiO K5 Pro Headphone amplifier

K5 Pro is equipped with AK4493EQ DAC chips from AKM - known for its smooth, pleasant and yet detailed sound due to its high signal-to-noise ratio and low distortion. It supports up to 768 kHz / 32 bits and bit depths, as well as native DSD.

When paired with the TI TPA6120 op-amp and OPA1642 JEFT op-amp, the NJRC NW1195A analog volume control chip, the K5 Pro delivers amazingly smooth, high-definition sound.

Using the ADC volume control can not only eliminate channel volume imbalances, but also allow the user to smoothly adjust the volume to a more accurate and fine level, improving the performance and sensitivity of your headphones.

With the K5 Pro you can switch between low, medium and high gain levels (depending on how much power your headphones need).

With the K5 Pro, we redesigned and further optimized the audio circuit to displace every last drop of potential from the TPA6120 for a total output power of up to 1.5 W at 32 ohms and up to 20 Vpp at 300 ohms.

Different connection options for different scenarios: Coaxial / Optical / RCA line-in + 6.34 mm (1/4 in.) Headphone outputs / RCA line-out.

Savršena kombinacija pojačala i DAC za slušalice uz relativno pristupačnu cijenu. Koristim ga za napajanje jako modificiranih Fostex T50RPmk3 50 Ohm slušalica i nemam problema, dovoljno snage na niskoj postavci pojačanja za puni zvuk cijelog frekventnog raspona uključujući jako gladne bass frekvencije.
