Key Specifications & Features

• G5 Silver-Gold Metallurgy: The SQ-110 Mk2 utilizes Siltech’s Generation 5 solid-core silver-gold alloyconductors (1.0 mm / ~18 AWG diameter per conductor). The inclusion of gold micro-injected into the pure silver crystal lattice fills atomic micro-cracks, significantly reducing signal boundary distortion and micro-dynamics loss.Reverb
• Dielectric & Insulation: Employs ultra-thin Kapton and PEEK insulation layers supplied by DuPont, which provide superior dielectric stability and durability compared to standard PTFE/Teflon constructions.Reverb
• Topology: Utilizes Siltech’s X-Balanced Micro Technology geometry, engineered for exceptionally low magnetic interference pickup, reduced inductance/capacitance, and ultra-low noise floor.Stereophile.com
• Connectors: Factory terminations typically feature high-grade Neutrik/WBT XLR 

Acoustic Characteristics

• Ultra-Low Noise Floor: Provides exceptionally black backgrounds and low micro-level distortion, allowing delicate ambient cues, dynamic micro-contrasts, and mechanical details to pass cleanly.Siltech Cables
• Tonal Balance: Known for neutral, liquid, and detailed reproduction without the top-end harshness or glare often associated with pure silver cables.Reverb
• Spatial & Imaging: Offers sharp focus, expansive 3D soundstaging, and distinct layer separation for complex orchestral or acoustic textures.Siltech Cables
