High-End Speaker Cable with 72V Dielectric-Bias System
Absolute transparency and total control of the signal
AudioQuest Type 9 + DBS is a speaker cable designed for reference Hi-Fi systems and high-end setups where every detail counts. It uses Perfect-Surface Copper+ (PSC+) conductors, featuring an extremely smooth surface that reduces grain distortion and enhances micro-harmonic information. The solid-core conductor construction eliminates the internal interference typical of multi-strand cables, ensuring greater coherence, soundstage focus and natural tonal quality. It is the ideal choice for high-resolution systems that require precision, dynamics and impeccable background silence.
Star-Quad geometry and DBS 72V technology
The low-inductance Star-Quad configuration improves electrical stability and optimizes bass control by reducing polar interaction. FEP (Fluoro-Polymer) insulation ensures an extremely low dielectric constant, limiting power consumption. The 72V DBS (Dielectric-Bias System) maintains a constant dielectric polarization, reducing distortion and improving signal smoothness right out of the box. The result is a more open, three-dimensional, and controlled sound.
Electrical stability and long-distance performance
Type 9 + DBS is designed to offer low resistance , reduced inductance , and parasitic capacitance control, maintaining high performance even with demanding speakers and significant lengths. Its robust construction makes it suitable for both dedicated installations and high-end home systems. It is a cable that enhances refined electronics and high-quality speakers, improving articulation, detail, and depth of the soundstage.
