The CH Precision approach to D/A conversion is designed with four uncompromising priorities…
Time-domain accuracy – ensuring transients arrive exactly when they should, preserving rhythm, flow, and musical drive
Continuity – delivering a seamless, natural signal with no discontinuities or artifacts to disrupt musical expression
Low-level resolution – retrieving the finest details buried deep within recordings, so ambience and microdynamics are never lost
Harmonic accuracy – preserving the tonal balance and natural timbre of instruments and voices without coloration or distortion
Unlike solutions that rely on off-the-shelf architectures, CH Precision DACs are completely bespoke and proprietary—fully engineered in-house from the ground up to achieve these goals without compromise.
Our innovations make this possible:
Software-defined R-2R ladder → all resistors fabricated on the same substrate for identical geometry, thermal balance, and long-term reliability, dramatically reducing mismatches and parasitics
PEtER algorithm → evenly distributes switching to prevent drift and ensure consistent performance over time
Spline filter → accurate in the time domain because it minimizes both pre- and post-ringing, preserving transient integrity while maintaining signal density and spectral balance
Together, these innovations ensure clarity, resolution, and natural coherence—music that flows with the ease, authenticity, and emotional impact of live performance.
