EverSolo FIA - Fully Isolated Architecture

The DAC-Z10 is built on Eversolo’s proprietary Fully Isolated Architecture (Eversolo

FIATM), which fully isolates the digital and analog domains to minimize interference and

preserve signal purity.

Dual AKM Decoding:

Another core element of the FIA design is the DAC-Z10’s dual AKM decoding

modules. Each channel is handled by a dedicated set of AK4191 + AK4499 chips,

meaning the left and right digital signals remain completely separated from input to

conversion. This design not only eliminates channel crosstalk but also enhances

dynamic range and resolution. Combined with AKM’s Velvet Sound™ technology, the

DAC-Z10 delivers audio that is both precise and delicate. Even at high specifications

—DSD512 and PCM 768 kHz/32-Bit—it maintains ultra-low distortion (THD+N

0.00008%) and wide dynamic range (DNR 130 dB), letting the music flow with the

energy and presence of a live performance.

Fully Balanced R2R Network:

The concept of “independent left and right channels” extends to volume control. The DAC-

Z10 employs a high-precision R2R resistor network, with separate R2R modules for each

channel. Unlike conventional digital volume, which can introduce quantization loss, the

R2R network preserves signal integrity and phase alignment at every step. From very low

to high playback levels, the sound remains pure and full, with every knob adjustment

resulting in precise analog-level changes. This is the essence of the DAC-Z10—capturing

every nuance of the music with the purest analog precision.

Extensive Connectivity:

The DAC-Z10 offers extensive connectivity options to meet the demands of high-end

systems. It features USB Audio in, dual coaxial in, dual optical in, IIS in, AES/EBU in,

and HDMI ARC input. The USB input employs a multi-core audio processor, supporting

DSD512 Native and PCM 768 kHz/32-bit lossless transmission. The IIS input provides

eight customizable modes to ensure compatibility with a variety of sources from different

brands. All inputs use electrical isolation to fully eliminate ground loop interference,

delivering every signal in its purest form.
