Product Overview
The iFi Audio ZEN Stream 3 is a pure, uncompromising audio transport designed to elevate your high-fidelity network streaming experience. Engineered as a dedicated, high-performance bridge between your network and your DAC, it completely bypasses the noisy, resource-heavy components of standard computers or basic streamers. Featuring a custom-built, open-source architecture that is heavily optimized for flawless, bit-perfect audio delivery, the ZEN Stream 3 ensures that your music arrives at your DAC with zero jitter, zero coloration, and breathtaking clarity. With enhanced 64-bit processing power, Active Noise Cancellation II technology on its outputs, and seamless integration with Roon, Tidal Connect, and Spotify Connect, it stands as the quintessential digital hub for any premier home audio ecosystem.

Key Features
- Bit-Perfect Architecture: A true high-res network bridge that passes the digital audio signal completely unaltered, ensuring the DAC receives an identical, bit-for-bit match of the original file.
- Exclusive Streaming Modes: Hardware and software dedicated specifically to individual platforms including Roon, Tidal Connect, DLNA, and HQPlayer NAA for the purest possible signal path.
- Active Noise Cancellation II (ANC II): Applied to the USB ports to actively detect and cancel out incoming electrical noise, significantly lowering the noise floor and improving dynamic contrast.
- GMT Femto-Precision Clock: Features iFi’s proprietary Global Master Timing clock system to eradicate digital timing errors and jitter, delivering a phenomenally smooth and natural soundstage.
- Advanced Connectivity: Outfitted with lightning-fast Wi-Fi 6 (Dual-band 802.11ax) and a Gigabit Ethernet port for ultra-stable, high-bandwidth streaming of heavy DSD and PCM files.
- iPurifier S/PDIF Output: The coaxial digital output features built-in iPurifier technology to re-clock and regenerate the signal, guaranteeing absolute purity when connecting to non-USB DACs.
