Supra EFF-IRB 2RCA - 2RCA

Supra EFF-IRB is a high-performance analog signal cable with angled RCA connectors, designed to deliver flawless transmission of even the subtlest nuances in music. 

• Rich overtones: The cable's design makes it easy to distinguish instruments and voices, thanks to precise transmission of overtone spectra.
  Dynamic soundstage: Experience powerful drum hits and nuanced phrasing highlighted with outstanding dynamics.
  
• Effective shielding: Reduces background noise and lets microdynamics flourish, creating a clean and detailed sound scene.
  
• High and low frequencies: Provides a three-dimensional soundstage with precise attacks and rhythmic details, including spatial information from the lowest frequencies.

Technical innovation

Supra EFF-IRB is designed to minimize current crowding (skin effect) and capacitance, ensuring smooth and accurate signal transmission across the entire frequency spectrum. With Equalized Frequency Flow (EFF) technology, where silver-plated conductors are spun around a tubular core, a uniform impedance is created that preserves sound level and timing. The low capacitance from the PE insulation and individual foil shielding help maintain sound purity and three-dimensionality.
