Audiolund RCA Interconnect Cable ~ Reference Series
Design & Construction
- Improved Construction: Revised RCA cable architecture for enhanced overall sound quality.
- Conductor Configuration: Uses 1 × 16GA + 1 × 20GA Duelund tinned copper wire for both positive and negative signal paths in a multi-wire configuration.
- Conductor Quantity: A 1.0-meter pair uses a total of 4m × 16GA + 4m × 20GA Duelund tinned copper wire.
- Multi-Layer Shielding: Multiple types and layers of shielding materials are applied to minimize noise and RFI/EMI interference.
- Advanced Damping: A dedicated damping structure incorporates various anti-vibration and damping materials to suppress and isolate unwanted mechanical vibration.
- Standard Length: 1.0 meter, with additional length options available.
- Connector: Carbon fiber connector.

Sound Characteristics
The Reference Series RCA Interconnect is designed to deliver excellent dynamics with smooth transitions across both high- and low-level passages. High sound density and a full-bodied presentation are complemented by a pure, refined, and musical character.
Its natural tonal texture conveys rich musical information with an engaging vinyl-like, analog presentation. The Duelund tinned copper conductors provide sonic characteristics reminiscent of the classic Western Electric (WE) sound, contributing warmth, musicality, and natural tonal balance.
The overall presentation is smooth, harmonious, and engaging, allowing musical melodies and textures to flow naturally for a relaxed and immersive listening experience.
Conductor Cross-Sectional Area: The Reference Series RCA Interconnect has an estimated conductor cross-sectional area of 1.83 mm² per meter, per +/- channel, using Duelund copper conductors.
Humble Comments
The Reference Series RCA Interconnect is designed to achieve a balanced presentation across the low, mid, and high frequencies, while retaining the characteristic musical qualities associated with Duelund and classic Western Electric-style conductors.
Its balanced tonal character makes it particularly suitable as a reference interconnect for a well-balanced audio system.
Performance & Value
The Reference Series RCA Interconnect is designed to deliver a high level of performance relative to its price, making it a strong reference point for comparison with other premium RCA interconnects.
Cable Run-In
Audiolund cables primarily employ multi-core designs with carefully selected combinations of conductors. As a result, sufficient run-in time is recommended for the cables to reach their intended performance.
OCC silver conductors, particularly thicker solid-core designs, generally require a longer run-in period than Duelund tinned copper conductors, which use multiple parallel fine strands.
As a general guideline, we recommend approximately 100–200 hours of run-in.











I’m already using unshielded diy RCA using 2 cores Duelund DCA16GA with Switchcraft plugs. This cable significantly outperformed my diy cable. It doesn’t change the sound character but the overall sound now sounded much richer with great body especially to the vocal and mid. The difference is immediately noticeable. I’m using the cable between pre and power amp where all the sources can benefit from the change.
The quality of the sound is noticeably enhanced the moment you turn on the power. Cost is reasonable and service is prompt and personable.
Fantastic product, great service.
This Interconnect RCA is value for money. I like the details and warm sound of this cable. It is much better than my current old cable. A good recommendation and good buy.
