Audioquest Angel RCA/RCA DBS 5m

AudioQuest Angel RCA/RCA DBS: the pinnacle of the Bridges & Falls series

This RCA cable is the top model in the Bridges & Falls series, the only one in this range to use solid silver conductors. AudioQuest designed this analog interconnect for systems where every detail matters, combining their proprietary technologies in a compact and flexible format.

Perfect-Surface silver conductors

Solid Perfect-Surface Silver (PSS) conductors eliminate strand interaction, a major source of distortion in stranded cables. High-purity silver also minimizes disruptions caused by grain boundaries present in any metal conductor. In practical terms, Perfect-Surface technology applied to very pure silver reduces sonic harshness compared with OFHC, OCC, or 8N copper.

This solid (non-stranded) structure transmits low-level signals more efficiently than a multi-strand cable. The difference is audible from the very first seconds: the system seems more present, more alive.

The 72-volt DBS system, an AudioQuest patent

The 72 V DBS (Dielectric-Bias System) saturates and polarizes the insulation, enabling clear, dynamic sound against a very quiet background. The principle is simple: any insulation slows the signal, but not uniformly across frequencies when it is not polarized. These differences in time delay are problematic for a multi-octave audio signal that is highly time-sensitive.

DBS creates a stable electrostatic field that organizes the molecules of the insulation. This minimizes both energy storage in the insulation and multiple non-linear time delays. The battery pack (included) lasts for several years and features a test button with LED to check its status. An RF trap, developed for AudioQuest’s Niagara power products, prevents radio-frequency interference from entering the conductors from the DBS elements.

FEP air-tube insulation

Any solid material adjacent to a conductor is part of an imperfect circuit: the insulation absorbs energy, stores part of it, then releases it as distortion. Air absorbs virtually no energy, and FEP (fluoropolymer) is the best extrudable solid insulation available.

The positive conductors benefit from near-zero contact between the metal and their FEP insulation, which has a low dielectric constant and minimal interference with the signal. The negative conductors use deliberately “lossy” insulation: no air, no FEP, to optimize their different function in the circuit.

Three-layer NDS shielding

Three alternating layers of metal and carbon-loaded synthetics “shield the shielding,” absorbing and reflecting most of the RF energy before it reaches the ground-connected layer. This carbon-based NDS (Noise-Dissipation System) prevents captured interference from modulating the component’s ground reference.

Asymmetrical double-balanced geometry

Designed for unbalanced (single-ended) applications, this geometry offers lower impedance on the ground for richer, more dynamic reproduction. While many unbalanced cables use a single path for ground and shielding, the double-balanced design separates them for cleaner, quieter performance.

The Bridges & Falls series houses the left and right channels in a single jacket, with asymmetrical double-balanced geometry and separate high-quality positive and negative conductors. This design allows for a thin, flexible, and versatile cable.

Solderless connectors

The RCA plugs are made of pure red copper with direct silver plating, assembled by cold welding. This design avoids conventional soldering, a frequent source of distortion. The ground shells are stamped rather than machined, making it possible to choose the metal for its low distortion rather than for ease of machining.
