Product Description
An all-in-one desktop HiFi DAC/headphone amp/preamp: With premium chipsets and self-developed fully balanced circuitry, low noise and low distortion. Perfect for HiFi headphones or active speakers, it's the ultimate desktop audio solution.
Exceptional Sound Quality: Premium chipset with AKM4493SEQ DAC, XMOS XU316 processor, and four OPA1612 amps supports up to PCM 768kHz/32bit & DSD512. A self-developed dual-power balanced amp circuit with multiple ultra-low-noise LDOs and capacitors keeps noise as low as 1.9μV.
High Output Power: Equipped with both 6.35mm single-ended (640mW@32Ω x2) and 4.4mm balanced (2570mW@32Ω x2) outputs. The 3-level gain switch supports headphones ranging from 16Ω to 300Ω, making it perfect for almost in-ears and over-ear headphones.
Versatile & Flexible: With coaxial, optical, USB, and RCA inputs, plus 4.4mm, 6.35mm, RCA, and XLR outputs, it connects to diverse audio sources and devices. Functions as a DAC/amp/preamp for desktop HiFi. UAC mode switching ensures full compatibility with game consoles for both music and gaming.
Rich Customization: Features bass/treble EQ adjustments and 6 filter types, including Bypass mode and two swappable op-amps, allowing you to customize the sound to match your preference. All functions are integrated into the screen for a clean, premium look that continues the Z-Series design language.
