The FiiO K11 R2R is the update of the successful K11 desktop amplifier/DAC with anew DAC structure and resistor array with 24-bit R2R chiptotally differentiating on the market.
It also incorporates dual NOS/OS modes and high-quality electronic volume control, all to offer power figures of 1300mW + 1300mWand three levels of gain.
With each component designed in detail to obtain maximum performance, the FiiO K11 R2R lands with new ways to listen to your music without interruptions. Find out!
The new 24-bit R2R four-channel fully differential DAC developed by FiiO, consists of two sets of maximum precision thin film resistors.
At a total of 192 resistors and a tolerance of 0.1% and low temperature deviation, it results in a unique and charming device.
Its totally differential architecture results in lower noise and a full musical background, compared to other current DAC/AMPs.
The FiiO K11 R2R has two modes of use: NOS mode and OS mode.
Support for 384kHz/24-bit PCM and DSD256 decoding means the K11 R2R can handle high-precision audio signals and display the details inside.
In turn, the NJW1195A is a four-channel electronic volume controller. The electronic resistor ladder potentiometer has low distortion and low noise, for a premium experience.
Thethree independent gain levels and volume curvesallow the K11 R2R to give you a better listening experience with different types of headphones, whether they are more sensitive IEMs or over-ear demanding to move.
The audio signal is transmitted through a USB interface processor to a digital audio bridge. After being processed by an FPGA, it is sent to the R2R DAC for 4-channel output after decoding. From there and through its two TI IOPA1642 op:amps, the volume is adjusted.
Its gain controls and all internal components are activated to protect your headphones, and of course, achieve a unique sound.
The ultra-low ESR of the capacitors, combined with excellent anti-interference capabilities, allows it to provide a stable and clean power supply for high-quality sound.
With a 32 Ohms load, the K11 R2R is capable of generating up to 1300mW + 1300mW in balanced mode. This allows you to easily handle premium headphones and unleash their full potential.
A durable, high-contrast custom LCD display lets you easily see sample rate, volume, gain, or output mode at a glance.
Additionally, the RGB-illuminated FiiO logo provides a quick way to identify the sample rate of the audio currently playing. Six LED strips work in conjunction with carefully placed reflective film and body parts designed to reflect light to make the light show uniform and elegant.
Themultifunction volume knob of the K11 R2R is used to turn the device on and off, to operate the menu, to adjust the volume and other functions. It is specially designed to perform multiple functions just by pressing and guiding it. You can also switch between modes and adapt your K11 R2R to different audio settings.
For greater stability, reliable connection and durability of the device, security systems are used through components designed to improve heat dissipation and protect the entire assembly with an exclusive phosphor copper metal shielding.
It also has DC protection and new energy saving system.
"Después de probar varios DACs con arquitectura Delta-Sigma convencional (como el FiiO K7), el paso al K11 R2R ha sido una revelación. Si buscas un sonido orgánico y musical por encima de la frialdad analítica, este dispositivo es imbatible en su rango de precio. Lo más destacado es, sin duda, su modo NOS (Non-OverSampling). La escalera de resistencias aporta una textura y un cuerpo a las voces y a los instrumentos que resulta muy difícil de encontrar en chips estándar. Los agudos son sedosos y naturales, eliminando cualquier rastro de estridencia o fatiga auditiva en sesiones largas. Lo utilizo principalmente con los auriculares FiiO FT1 (madera) por la salida balanceada de 4.4mm y la sinergia es absoluta. Al reproducir archivos a 192.0 KHz, la escena sonora se vuelve amplia y muy bien posicionada, con un timbre cálido y una densidad en los medios que hace que la música se sienta 'viva'. Puntos fuertes: Modo NOS: Sonido analógico real, ideal para grabaciones acústicas, jazz y voces. Potencia: Mueve con autoridad desde auriculares dinámicos hasta planares exigentes. Estética y funciones: El acabado en aluminio plata es premium y el menú permite personalizar el brillo y la información en pantalla de forma muy intuitiva. Fondo negro: Con una buena cadena de cables, el silencio de fondo es total. A mejorar: El cable USB que incluye de serie es básico; el aparato agradece mucho el salto a un cable USB-C de mayor calidad y blindaje para exprimir todo su potencial. En definitiva, FiiO ha dado en el clavo con esta implementación R2R. Es un equipo para disfrutar de la música, no solo para analizarla."
Saludos ! Encantado con este R2R y los Sundara con cable balanceado. En mi opinión es un sonido neutro, sin potentes bajos ni cristalinos agudos, lo cual hace que la escucha sea muy agradable, nada cansina. Muy contento ! El servicio de Zococity, como siempre, genial.
Eficaz
Despues de escucharlo, me ha encantado, es suave y detallado, potencia de sobra tanto para auriculares como para calidad de salida de linea , para el precio que tiene es un producto magnifico, en calidad y construccion
