Eversolo DAC-Z10

DAC 2x AK4499 + AK4191 I2S HDMI ARC Bluetooth 5.0 32bit 768kHz DSD512

The Eversolo DAC-Z10 is a high-end digital-to-analog converter designed for demanding audiophiles, combining technical precision and musicality. It features a fully isolated architecture (FIA), which physically and electrically separates the digital and analog circuits to minimize interference and preserve signal purity. Equipped with two AKM decoding chips (AK4191 + AK4499EX) per channel, it offers high-resolution conversion up to 32-bit 768kHz PCM and DSD512, ensuring highly refined sound reproduction with low distortion.

The DAC-Z10 incorporates a high-precision clock system, the Eversolo Precision Core, combining a temperature-controlled crystal oscillator (OCXO), PLL technology, and FPGA clock reconstruction to ensure optimal time consistency and reduced jitter. Its R2R volume control and integrated preamplifier enable analog signal management, while its comprehensive connectivity makes it a versatile device suitable for HiFi systems, home theater setups, and headphone listening. With a total harmonic distortion plus noise of 0.00008 percent and a dynamic range of 130dB, this DAC delivers extremely high-fidelity performance.

Eversolo DAC-Z10: Fully Isolated FIA Architecture

The DAC-Z10 is built on Eversolo’s fully isolated architecture, separating digital and analog sections to minimize interference. Three independent linear power supplies individually power the left channel, system, and right channel, ensuring a low-noise environment. Its decoding architecture includes two independent sets of AK4191 + AK4499 DACs for left and right channels, combined with a fully balanced analog preamplifier and dual-channel R2R volume control for high dynamic range and low THD+N.

Eversolo DAC-Z10: Three Independent Power Supplies

With three independent toroidal transformers powering the left channel, right channel, and system, the DAC-Z10 maintains ultra-low noise down to 42µV. This design minimizes interference and provides stable, detailed sound.

Eversolo DAC-Z10: Dual Decoding Modules

Designed with a symmetrical architecture, the DAC-Z10 features two independent AK4191 + AK4499 DAC modules for left and right channels. Combined with AKM’s Velvet Sound technology, it provides precision and tonal richness while supporting PCM up to 32-bit 768kHz and DSD512.

Eversolo DAC-Z10: R2R Volume Control

The DAC-Z10 uses a precise R2R resistor network for volume control, preserving the original signal at all levels and maintaining clear and accurate sound.

Eversolo DAC-Z10: Fully Balanced Preamplifier

The fully balanced preamplifier includes XLR and RCA analog inputs offering up to +10dB gain. Together with the R2R volume control, it maintains ultra-low noise and distortion for improved dynamic range and signal integrity.

Eversolo DAC-Z10: Phase-Locked Loop Technology

The DAC-Z10 employs an OCXO temperature-controlled quartz oscillator and PLL technology for precise clock reconstruction. This ensures stable synchronization and accurate sound reproduction.

Eversolo DAC-Z10: External Clock Support

The DAC supports 10MHz or 25MHz external clocks and includes both 50Ω and 75Ω inputs for maximum precision.

Eversolo DAC-Z10: FPGA

An integrated FPGA shapes I2S data and refines the clock, optimizing digital signals before conversion.

Eversolo DAC-Z10: High Accuracy and Low Distortion

With ultra-low THD+N of 0.00008 percent and a dynamic range of 130dB, the DAC-Z10 reproduces music with exceptional clarity.

Eversolo DAC-Z10: Multi-Core USB Audio Processor

The multi-core USB audio processor enables high bandwidth and lossless transmission, supporting PCM 32-bit 768kHz and DSD512 via USB. Optical and coaxial inputs support up to PCM 24-bit 192kHz and DSD64 DoP.

Eversolo DAC-Z10: Grounding Terminal

A grounding terminal is included to dissipate noise and preserve signal purity.
