For those seeking precise sound reproduction and authentic analog signal conversion, R2R technology is the ideal choice. R2R DACs convert digital signals into true analog signals through a resistor network. Unlike the widely used Delta-Sigma (Δ-Σ) and 1-bit technologies, which approximate analog signals by modulating digital data into sequences of 0s and 1s, R2R DACs avoid these inherent errors and can accurately reproduce even DC signals.

Proprietary R2R Architecture
Our design features 32 ultra-high-precision resistors per channel, totaling 64 resistors, to form a fully discrete R-2R DAC circuit. With 64 resistors each offering a 0.1% tolerance, this uncompromising precision ensures unmatched audio fidelity.

Meticulous Sound Tuning
At HeartField, we believe the essence of any HiFi product is in its tuning. Advanced technology alone isn't enough—without careful sound craftsmanship, the result is lifeless. Exceptional tuning brings music to life, making every note resonate. HeartField—Experience a world where every note is full of vitality.
