OBSESSION:  

• Position: The entry-level offering that pioneered Echole's use of solid-core alloy in speaker cables.  
• Description: Features a 0.6 mm solid core design and hand-braided construction that delivers a clear and open sound. In contrast to later models like Signature or OMNIA, its simpler build suits buyers with modest budgets and small-room setups.

SIGNATURE:  

• Position: A reference-grade cable known for its balanced performance and long burn-in process.  
• Description: Features a 1.1 mm solid core and palladium-polished terminations. Compared to OBSESSION's straightforward design and OMNIA's more mainstream appeal, it offers refined technical performance.

ORIUS:  

• Position: A cable positioned just below the mid-tier level for clear and transparent sound.  
• Description: Uses a 1.4 mm solid core with a highly refined alloy and simple terminations. While it shares many characteristics with the OMNIA series, its lower cost and slightly reduced performance make it well-suited for smaller listening spaces.

OMNIA:  

• Position: A mid-tier best-seller designed for natural sound reproduction with a focus on everyday performance.  
• Description: Uses a 1.55 mm solid core and high-grade alloy construction. In comparison to Orius' entry-level simplicity and Limited Edition's advanced features, OMNIA strikes a balanced compromise for users needing reliable performance without the premium price.

LIMITED EDITION:  

• Position: A high-end cable that elevates performance above the OMNIA series through enhanced harmonic resolution.  
• Description: Features a 1.75 mm solid core fashioned from a custom-structured alloy to heighten dynamic contrast. When set against OMNIA's mainstream design and Infinity's ultra-premium build, it fits users seeking improved technical precision while remaining below the flagship price level.

INFINITY:  

• Position: The flagship speaker cable line featuring the most complex design with the highest quality materials in the range.  
• Description: Features a 2.10 mm solid core made from thick Silver/Gold/Palladium alloy, a groundbreaking technology that brings studio-level performance into a home setting. In contrast to the Limited Edition's high-level refinement and other models' more modest builds, Infinity represents ultimate technical sophistication, expansive soundstage, and top-tier functionality.
