FIIO K13 Compact Desktop R2R architecture DAC and Headphone Amplifier (Black) 18290{1}1
Fully differential true 24Bit R2R resistor arrays DAC - FIIO’s proprietary four-channel fully differential 24-bit R2R resistor array DAC is composed of 48 precision thin-film resistors per channel, for a total of 192 resistors across four channels. Each resistor features 0.1% accuracy and low temperature drift (30ppm). This R2R DAC allows the K13 R2R to deliver a uniquely rich and musical sound. Comparison between fully differential and typical architectures - The K13 R2R employs a fully differential architecture that leads to lower noise and fewer FFT harmonics, resulting in a darker music background. Preamplifier + power amplifier output With a wide variety of inputs and outputs, this unit functions as both a preamplifier and a power amplifier, catering to various listening preferences. It also supports PCM 384kHz/32bit and DSD256 decoding, allowing it to effortlessly process high-resolution audio signals to deliver rich sonic detail and for an outstanding listening experience. Fully balanced audio amplifier circuit - The entire audio chain, including the R2R DAC, LPF, volume control, and headphone amp, uses fully differential signal processing for excellent interference rejection, minimal distortion, and high dynamic range. The amplification circuit also features gain control, headphone protection mechanisms, and POP noise elimination for a robust and reliable audio experience. Multi-rail power supply – Robust performance. With up to 18 low-noise LDOs and 5 DC-DC converters in total, this unit employs a multi-rail power supply to provide strong and clean power for exceptional audio output. Robust output - Revealing every last detail. Boasting a balanced output power of 2400mW+2400mW into a 32Ω load, the K13 R2R can effortlessly drive both high-fidelity IEMs and headphones, unlocking their full potential and allowing them to render every last detail. Superior screen and clarity - A custom, high-contrast, long-lasting HD LCD display* clearly shows the device’s current status at a glance, including sampling rate, volume, gain, and output mode. *Long-lasting LCD display, can always be on without risk of burn-in Minimalist design - technological elegance. The thickened, unibody aluminium alloy casing, paired with a brand-new “skylight” design, not only continues the K11 series’ minimalist design language but also introduces a literal technological window into the R2R resistor series. The flowing light and vibrant colours showcase a unique tech aesthetic. LDAC high-res Bluetooth - Truly enjoy wireless HiFi. With support for Bluetooth 5.4 and reception for the LDAC/AAC/SBC codecs, the K13 R2R allows you to be immersed into in a world of high-quality music even when listening wirelessly. Precisely designed - Perfect performance. Three gain levels, three independent volume curves. Different gain levels mean the K13 R2R is better able to adapt to various kinds of IEMs and headphones for better listening experiences. Moreover, volumes of PO and PRE can be memorised independently.

FIIO K11 Compact Desktop R2R architecture DAC and Headphone Amplifier (Black) 17650{1}1
Fully-Differential 24-Bit R2R DAC Array - FiiO has featured its newly developed four-channel fully differential 24-bit R2R resistor array on the K11 R2R. It consists of 48 resistors per channel, a total of 192 high-precision ultra-thin film resistors with 0.1% accuracy and low-temperature drift between the four channels. It promises clean and crisp output with dark background thanks to the specially developed audio circuit architecture. NOS/OS Dual Operating Modes - FiiO K11 R2R has NOS(Non-Oversampling) and OS(Oversampling) dual operating modes. These are freely switchable and offer dual sound characteristics with the device. The NOS mode maintains the original sampling rate while signal processing while the OS mode oversamples all the signals to 384kHz for processing. NOS mode results in more musical presentation while the OS mode delivers more details and clarity. Powerful Amp Section - FiiO has equipped the K11 R2R with professionally designed amp circuitry. It consists of Ti OPA1642 as Low-Pass filters and then dual SGM8262 Professional-grade operational amplifiers. The K11 R2R has an output power rating of up to 1300mWx2, which is adequate enough to drive demanding headphones with ease. It has three-level gain modes for easy pairing with sensitive as well as high-power requiring gear. The K11 R2R also adopts NJW1195A precise digital volume chipset for precise volume adjustment with low distortion between the channels. Dual Headphone Output Ports - FiiO K11 R2R houses dual headphone output ports. It consists of a single-ended 6.35mm port and a balanced 4.4mm output port. You can easily pair different IEMs and headphones with the K11 R2R and enjoy high-resolution music to all its glory. True High-Resolution Audio Signal Processing - FiiO K11 R2R supports decoding for high-resolution audio signals. It has full support for PCM and DSD signal processing supporting up to 32-bit/384kHz PCM and DSD256 audio signals. DSD256 requires the DSD output mode to be set to native. It is internally converted into PCM for R2R signal processing. Professionally Designed Low-Noise Power Supply - FiiO K11 R2R features a professionally designed low-noise power supply. It consists of 17 Low-Noise LDO precision voltage regulator ICs and 2 DC-DCs providing a multi-channel power supply.
