What is an R2R DAC and why does it matter?

It converts digital to analog with a resistor ladder instead of a single chip. Fans say it sounds smoother and less clinical; it measures worse on paper than delta-sigma designs.

Can it drive planar magnetic headphones?

Yes. The 2400mW output is enough for most planar and high-impedance dynamic headphones, and the balanced output gives extra headroom.

Does it work as a preamp for speakers?

Yes. It has balanced XLR and single-ended RCA line outputs, so it can feed active speakers or a power amp with volume control.

What Bluetooth codecs does it support?

LDAC is the headline codec, aimed at high-resolution streaming from Android phones and some players. It is not a full wireless ecosystem.

What is the 10-band PEQ for?

It is a parametric equalizer built into the DAC. You can correct headphone peaks or add bass without extra software on your computer.

What comes in the box?

The unit, its external power supply, and the usual cables and documentation. Check the listing for the exact accessory set.

Our take on the FiiO K13 R2R Desktop DAC & Headphone Amp

The FiiO K13 R2R is a desktop DAC and headphone amp built around a 24-bit R2R resistor-ladder converter rather than the delta-sigma chips most amps in its class use. It drives headphones with up to 2400mW of output, adds LDAC Bluetooth streaming, a 10-band parametric EQ, and balanced XLR plus RCA line outputs. It suits desktop listeners who want R2R tonality and a built-in EQ without stacking separate boxes, and it competes with chip-based desktop DAC/amps by offering more input flexibility and tuning than most of them.
