FiiO BTR3K

The BTR-3K headphone amplifier offers a fully symmetrical design for uncompromising sound. It contains a pair of AK4377A DACs (converters), which provide great sound. From the higher model BTR5, the BTR-3K takes dual crystal oscillators 22.5792M / 22.576 MHz, thanks to which it can more faithfully reproduce audio signals of various sampling frequencies and reduce jitter when decoding from USB and Bluetooth. The amplifier itself is housed in an aluminum case with a 2.5D glass shell, as with modern smarphones. The oleophobic layer then prevents fingerprints from adhering to his body.
