FiiO WARMER R2R – Fully Balanced Tube-Buffered R2R DAC & Preamp

The FiiO WARMER R2R blends a precision 24-bit R2R resistor-array DAC with a four-tube buffer stage, creating a warm, musical and richly textured sound while keeping modern digital clarity and flexibility. It’s designed for listeners who want analogue charm with high-fidelity performance — dostępny w Soundium.

Kluczowe cechy

• Fully differential 24-bit R2R DAC: Built with 192 thin-film resistors for low noise, natural detail and an organic analogue-like signature.
• Four JJ Electronic E88CC tubes: Tube buffer stage adds warmth, sweetness and harmonic richness without sacrificing resolution.
• USB, optical and coaxial inputs: Connect phones, computers, CD transports and digital players with simple input switching.
• Balanced and unbalanced outputs: RCA and XLR line outputs can be used simultaneously for flexible system integration.
• NOS/OS modes: Choose non-oversampling for purist playback or oversampling to 384 kHz for increased clarity and definition.
• Retro mechanical VU meters: Warm LED-backlit meters move with the music, adding a vintage visual touch.
• 46 W toroidal linear transformer: Low-noise, high-efficiency power supply ensures clean power delivery and stable performance.
• Vintage-inspired chassis: Classic square-and-round design with efficient ventilation for long-term reliability.

Korzyści

The WARMER R2R brings together the precision of R2R decoding and the musicality of tubes, making it ideal for anyone who wants depth, richness and smoothness in their system. Its broad input and output support makes it easy to pair with active speakers, stereo amps, headphone amps or DACs. Whether you prefer a softer, analogue feel or a clear, modern presentation, the NOS/OS switch and tube stage let you shape the sound to your taste.
