iFi SPDIF iPurifier Hi-Res 24bit/192kHz REclock Jitter Elimination
The iFi SPDIF iPurifier is engineered to significantly enhance the quality of digital audio signals from SPDIF sources, ensuring your sound matches the visual experience. It delivers a fully restored, jitter-free signal by employing a comprehensive 4-stage process: isolation, regeneration, memory buffer, and re-clocking. This results in improved dynamic contrast, warmer sound, and sharper detail. It proudly supports Bit-Perfect signal transfer, handling high-resolution formats up to 192 kHz, 24 bits, DSD, DoP, and even Dolby Digital and DTS. The unit also features galvanically isolated output to eliminate electrical interference, ensuring clean, interference-free audio.

What customers say
Audiophiles highly praise the iFi SPDIF iPurifier for significantly improving digital audio quality. Users consistently report that it effectively resolves common jitter and signal integrity issues inherent in S/PDIF connections. The resulting sonic improvements are described as increased clarity, a smoother presentation, and tighter bass response. Many feel it reveals previously obscured details, enhancing soundstage depth. While build quality is excellent, its value is most apparent when upgrading older or budget sources struggling with digital harshness. For listeners seeking maximum refinement in their digital chain, this device is often considered an essential solution, though improvements may be marginal in systems already featuring robust jitter rejection.
