Cayin RU6, experience R2R technology

The basic idea of an R2R ladder has 2 matched resistors at its core. The first one takes the name "R" and the other one "2R" which has the double value of R.

To achieve 24 bit decoding, 48 pieces of resistors (23xR and 25x2R) are needed for one channel for a total of 96 pieces for stereo.

R2R technology is known to provide a realistic and natural sound that offers a different experience for audiophiles.

To achieve this 24-bit decoding with R2R technology Cayin has selected resistors that can offer high precision while remaining stable to temperature changes.

Selectable NOS and OS modes

  • Non-Oversampling (no oversampling)
    • Maintains original sampling frequency in source bits
    • No digital filters, no post-processing, time-domain optimized, low phase distortion and jitter, no ringing artifacts
    • Musical and vivid sound, very natural, organic and coherent
  • Oversampling (with oversampling)
    • Increase sample rate by interpolation before Digital-to-Analog conversion
    • Improved resolution, reduced noise and improved anti-aliasing, optimized in the frequency domain.
    • Impressive detail and extended frequency, clean and detailed presentation with full dark background.

Discrete control volume

R2R circuits are very demanding when it comes to data integrity, mobile digital volume controls can severely damage the sound.

Since the usual volume control options cannot reach high standards of accuracy, low noise and low power consumption Cayin have developed their own volume control using a discrete array of resistors.

The 0-99 volume steps are controlled by 9 segments of resistors and relays which meet transparency standards to maintain the natural sound signature of this R2R DAC.

Intuitive and versatile

  • Volume buttons are also used to navigate through the menu
  • 1" OLED display shows all settings clearly and with good visibility
  • 3.5mm and 4.4mm balanced headphone output to suit your headphone collection

Dual construction on two motherboards

To minimize interference, the circuitry that makes up the Cayin RU6 is divided into two backplanes with the digital circuitry separated from the analog circuitry.

Safeguarding the integrity of the signal ensures that noise that may be created by the reference clock or DSP does not interfere with the amplifier circuitry.

High compatibility due to low power consumption

The discrete R2R is a DAC circuit with very low power consumption when compared to other integrated chipset DACs, minimizing power drain from the cell phone acting as the source.

As a connection, an interference shielded USB-C connector is used making it compatible with a wide range of mobiles, computers and players.

The Cayin RU6 is compatible with:

  • iOS and iPadOS
  • MAC computers
  • Windows 7, 8 and 10 computers
  • Android phones and tablets
  • Hi-Res players

High resolution and high fidelity

  • PCM: Support up to 384kHz
  • DSD: Support for DSD64/128/256

Allows you to select the gain between low and high to make it compatible with high sensitivity In Ear headphones.

Small and transportable

With its weight of only 28g and its very compact size, it fits in any pocket.

¡El Cayin RU6 es un fenómeno de suprema calidad y musicalidad!
Así es como clasifico este pequeño gran dongle.
Único en su concepto, con arquitectura R-2R, lo que esta pequeña maravilla puede hacer por su audición supera con creces su valor.
Tengo daps de gama alta, por valores de 3000€ y el RU6, les rivaliza directamente.
Escenografía holográfica, clipping, docilidad y emoción. No le falta nada a este equipo acústico de bolsillo.
Tengo una Hiby R3 Pro Saber, que se detuvo, debido a otros equipos más avanzados, pero con el uso de la RU6, la Hiby comenzó a tener una nueva vida. Excelente dap, la R 3 pro saber, probablemente la mejor en su segmento.
Sin embargo, el RU6 eleva el nivel a un nivel en el que gravitan los grandes monstruos de la gama alta, por valores extremadamente asequibles.
Este es mi compañero incondicional para la movilidad. Pequeño, fácil de guardar en el bolsillo, con una gran alma musical.
Imprescindible para cualquier apasionado de la música en su máxima expresión.

Muy buena buena experiencia.
El Cayin RU6 es absolutamente impresionante.
La calidad de sonido es brutal.
Si se conecta por la entrada 4,4 balanceada incrementa la potencia notablemente.
En mi caso, con unos senheiser he 650 y un iPhone, la calidad que aporta es extraordinaria.
Recomendable sin lugar a dudas.
