It pairs a warm, organic R2R character with enough clean power to drive demanding headphones, plus the inputs to sit at the centre of a desktop hi-fi or headphone rig. A capable all-in-one for audiophiles and headphone listeners, available at Soundium.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrue 24-bit fully differential R2R ladder DAC:\u003c\/strong\u003e A four-channel resistor array with 48 precision thin-film resistors per channel (192 total), 0.1 percent accuracy and low 30 ppm drift for a natural, musical sound.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNOS and Oversampling modes:\u003c\/strong\u003e Choose NOS for unaltered R2R tone, or oversampling at 384 kHz for extra clarity and detail.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-power balanced output:\u003c\/strong\u003e Up to 2400 mW + 2400 mW into 32 Ω balanced and 1220 mW + 1220 mW single-ended, with three gain levels for high-impedance headphones.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide digital connectivity:\u003c\/strong\u003e Dual USB-C, coaxial and optical inputs plus Bluetooth 5.4 with LDAC, AAC and SBC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull output set:\u003c\/strong\u003e 4.4 mm balanced and 6.35 mm single-ended headphone outs, plus balanced XLR and RCA line\/pre-outs to feed active speakers or a power amp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-band PEQ and digital filters:\u003c\/strong\u003e Tune the sound with a 10-band parametric EQ in the FiiO Control app, selectable digital filters, and an HD LCD showing sample rate, gain and output mode.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCustomer Benefits\u003c\/h4\u003e\n\u003cp\u003eThe K13 R2R gives you the warmth and nuance of a resistor-ladder DAC without giving up power or flexibility. Balanced and single-ended outputs drive everything from sensitive IEMs to 600 Ω studio headphones, while the line and pre-outs let it double as the heart of a desktop speaker system. Switch between NOS and oversampling, dial in the parametric EQ, and match gain to your headphones to land exactly the tone you want, from relaxed listening to detailed, analytic playback.\u003c\/p\u003e\n\u003ch4\u003eQuick Specs\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDAC type:\u003c\/strong\u003e Fully differential 24-bit R2R resistor ladder (192 thin-film resistors)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported formats:\u003c\/strong\u003e PCM up to 384 kHz\/32-bit, DSD up to DSD256 (USB); coaxial 192 kHz\/24-bit, optical 96 kHz\/24-bit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone outputs:\u003c\/strong\u003e 4.4 mm balanced and 6.35 mm single-ended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine outputs:\u003c\/strong\u003e Balanced XLR and RCA (switchable line-out\/pre-out)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput power:\u003c\/strong\u003e 2400 mW + 2400 mW balanced; 1220 mW + 1220 mW single-ended into 32 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth:\u003c\/strong\u003e 5.4 with LDAC, AAC and SBC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-to-noise ratio:\u003c\/strong\u003e 116 dB or higher (A-weighted)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions and weight:\u003c\/strong\u003e 21.0 × 18.8 × 4.2 cm, 980 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIn the Box\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eFiiO K13 R2R unit\u003c\/li\u003e\n\u003cli\u003eUSB-C cable\u003c\/li\u003e\n\u003cli\u003eAC power cord\u003c\/li\u003e\n\u003cli\u003eDocumentation and safety guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIdeal For\u003c\/h4\u003e\n\u003cp\u003eAudiophile desktop setups, headphone enthusiasts who want both power and R2R warmth, and listeners who want one hub for wired and Bluetooth sources.\u003c\/p\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eWorks with Windows, macOS and Linux over USB, plus coaxial, optical and Bluetooth sources; pairs with balanced or single-ended headphones, active speakers or a power amp via the line\/pre-outs.\u003c\/p\u003e\n\u003ch4\u003ePros and Cons\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003e✅ Pros:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWarm, natural sound from a true R2R resistor-ladder DAC\u003c\/li\u003e\n\u003cli\u003eHigh balanced output drives demanding, high-impedance headphones\u003c\/li\u003e\n\u003cli\u003eFlexible I\/O with balanced and single-ended outs plus line\/pre-outs\u003c\/li\u003e\n\u003cli\u003eBluetooth 5.4 with LDAC alongside high-res wired inputs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Cons:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNo analog input, so it cannot digitise turntables or other line sources\u003c\/li\u003e\n\u003cli\u003eLarge desktop footprint and 980 g weight take real desk space\u003c\/li\u003e\n\u003cli\u003eHigh-res PCM and DSD only over USB; optical caps at 96 kHz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWith its R2R warmth, high-power balanced amp and full set of inputs and outputs, the FiiO K13 R2R works as a complete desktop centrepiece.
