FiiO WARMER R2R, Desktop DAC and Amplifier: Fully Balanced 24Bit R2R Resistor Array JJ E88CC Tube Buffer DAC/AMP

FiiO Warmer


Key Features:

Proprietary Fully Balanced R2R DAC Architecture
- 24-Bit R2R Resistor Arrays: Implements a proprietary, four-way fully differential 24-bit R2R DAC, built with a total of 192 high-precision thin-film resistors (48 per channel) with 0.1% accuracy and an ultra-low drift of 30ppm for a rich and organic sound signature.
- Dual NOS/OS Modes: Offers both Non-Oversampling (NOS) and Oversampling (OS) modes, allowing users to switch between a more authentic, organic sound and a more refined, clear audio presentation.

JJ Electronic E88CC Tube Buffer Stage
- Quad Vacuum Tubes: Features four brand-new JJ Electronic E88CC vacuum tubes imported from Slovakia, powered by a ±28V power supply, to impart a sweet, organic tube flavor for a rich and full sound.
- Long Service Life: The tubes are specified with a long-lasting service life of approximately 10,000 hours.

Extensive Connectivity and Output Options
- Multiple Digital Inputs: Comes with three digital inputs: USB Type-B, optical, and coaxial, providing flexible connectivity to various audio sources. The USB input supports PCM signals up to 32-bit/384kHz and DSD256.
- Dual Analog Outputs: Equipped with both RCA and balanced XLR outputs, which can be used simultaneously, for connection to a wide range of amplifiers and powered speakers.

Low-Noise Linear Power Supply & Retro Design
- 46W Toroidal Linear Power Supply: Utilizes a 46W low-noise, low-ripple toroidal audio linear transformer to feed the device clean power, contributing to pristine and immaculate sound reproduction.
- Dual-Channel Analog VU Meters: Features extra-large, two-channel LED-backlit analog VU meters with a warm hue, providing visual feedback that moves in harmony with the music.
