HiFi Man Goldenwave SERENADE Jr DAC Headphone Amplifier
Frequently Bought Together
Product Overview & Specifications
The HIFIMAN GoldenWave Serenade Jr is a high-performance desktop R2R DAC, discrete Class-A headphone amplifier, and network streamer engineered for exceptional sonic realism and musicality. At its core, the Serenade Jr features dual proprietary HYMALAYA LE R2R DAC modules, delivering up to 32-bit/768kHz PCM and native DSD512 decoding over LAN streaming for precise, natural sound reproduction with ultra-low distortion.
Designed with a fully discrete Class-A amplification circuit driven by a 50W toroidal transformer and nearly 30,000 µF capacitor bank, the Serenade Jr delivers robust power—up to 3000mW at 32Ω balanced—to easily drive demanding planar magnetic headphones. Its capacitor-free analog path utilizes FET operational amplifiers and discrete LPF stages to eliminate non-linear distortion, providing an exceptionally pure signal across front-panel 4.4mm, 4-pin XLR, and 6.35mm headphone outputs.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Dual HYMALAYA LE R2R DAC Modules: Precision ladder DAC architecture built with 0.01% resistors to eliminate zero-crossing distortion for smooth, natural tonality.
- Discrete Class-A Headphone Amplifier: Inherits topology from reference-grade amplification to deliver warm mid-bass depth, transparent imaging, and massive headroom.
- High-Resolution Network Streamer: Integrated LAN Ethernet interface supporting local NAS playback, AirPlay, and high-bitrate streaming up to PCM 768kHz and DSD512.
- Capacitor-Free Discrete LPF Circuit: Eliminates coupling capacitors in the signal path to prevent electrolytic distortion and preserve full-range transient speed.
- 50W Toroidal Power Supply: High-purity iron core transformer paired with a 30,000 µF multi-stage filter capacitor array for ultra-clean DC power delivery.
