LHY AS8 Pro+ Audio-grade Network Switch

LHY Audio's AS8 Pro+ represents a refined evolution of its acclaimed predecessor, engineered to minimize internal noise and maximize sonic clarity. This 2026 flagship network switch builds on proven architecture with enhanced component selection, improved electromagnetic shielding, and optimized clock and power delivery systems. The result is a comprehensively designed solution that elevates network audio performance through meticulous attention to signal integrity and interference reduction.

LHY Audio's AS8 Pro+ redefines the standard for premium data conditioning in 2026, advancing the reference-level performance benchmarks that discerning audiophiles expect from contemporary network infrastructure. 

At the heart of the AS8 Pro+ lies a military-specification SC-CUT OCXO oscillator delivering exceptional phase noise performance of -112 dBc/Hz at 1Hz offset, ensuring timing precision that elevates network audio fidelity. The oscillator resides within a dual-chambered, precision-machined aluminum enclosure that isolates its delicate circuitry from external electromagnetic disturbances while maintaining thermal stability. This marriage of engineering rigor and refined aesthetics—completed with LHY Audio's signature engraving—exemplifies the meticulous craftsmanship underlying the AS8 Pro+'s performance.

The AS8 Pro+ incorporates LHY Audio's proprietary MagSheild™ technology to suppress electromagnetic interference and inter-component coupling, preserving signal purity throughout the signal chain. Power delivery is fortified with twelve Vishay BC056 reservoir capacitors—double the AS8 Pro complement—ensuring stable current supply and a lower noise floor. A precision PLL clock synthesizer distributes ultra-low-jitter 10MHz timing to both 1G and 2.5G network domains with exacting accuracy. Internal wiring throughout employs Oyaide 102SSC Super Silver Copper conductors, identical to those found in LHY's Ultimate Series DC cables, maximizing conductivity and minimizing resistance-induced signal degradation. Every unit ships with a serialized OCXO Phase Noise and Allan Deviation test certificate, providing documented assurance of measured performance and manufacturing integrity.

Features

• All the features of the LHY AS8 Pro with further upgrades
• Upgraded Clock: The AS8 Pro+ integrates a newly engineered military-specification SC-CUT OCXO oscillator with phase noise performance exceeding -112 dBc/Hz at 1Hz offset, delivering the timing precision essential to network audio excellence. Housed within a dual-chambered, precision-machined aluminum structure, the oscillator benefits from thermal stabilization and robust shielding against external electromagnetic disturbances. The refined enclosure, adorned with LHY Audio's distinctive branding, seamlessly unites technical mastery with understated elegance.
• MagSheild™ Shielding: Incorporates LHY Audio’s proprietary MagSheild plates, which dramatically reduce electromagnetic interference (EMI) and magnetic coupling between components. This ensures a cleaner signal path and minimizes jitter caused by internal noise. 
• Enhanced Power Supply: Utilizes 12 × Vishay BC056 high-grade reservoir capacitors (vs. 6 on AS-8PRO), delivering greater current stability and lower noise floor.
• Superior Clock Architecture: Features a top-tier PLL clock synthesizer that distributes ultra-precise 10MHz signals to both the 1G and 2.5G network zones.
• Upgraded Internal Wiring: All internal connections are upgraded to Oyaide 102SSC conductors, the same as used in our Ultimate Series DC Power Cable. 102SSC (Super Silver Copper) offers extremely high conductivity and low resistance, improving signal integrity and maintaining ultra-low noise transmission throughout the system.
• Dual High-Performence Toroidal Tranformers for Power supply: To isolate power-related interference and minimize cross-system interaction, AS8 Pro+ employs two NORATEL “Porcupine” toroidal transformers, providing fully independent power channels for the clock system and the switching circuitry. This design ensures that the 10 MHz master clock and its distribution modules operate under stable and isolated power conditions, supporting higher clock precision. At the same time, it delivers robust and stable power to key modules including the 2.5G/1G main controllers, SFP optical ports, and isolation zones.
• Test Certification Included: Each unit is shipped with a serialized, traceable OCXO Phase Noise and Allan Deviation Test Report, assuring measured performance and quality
