Description
Designed and handcrafted using carefully selected combinations of Duelund tinned copper and 5N OCC silver conductors, the Xtreme Silver Series is meticulously fine-tuned to achieve exceptional sound quality while minimizing signal transmission loss.
Important: Due to its extensive conductor count and advanced multi-core construction, the Xtreme Silver Series RCA cable is relatively large and heavy. Please inform us if your equipment has limited RCA connector clearance or space constraints.
Audiolund RCA Interconnect Cable ~ Xtreme Silver Series
Cable Construction & Design
- Improved Construction: Revised RCA cable architecture for enhanced overall sound quality.
- Each positive and negative signal path uses 1 × 12GA + 1 × 20GA Duelund tinned copper conductors, combined with 5N OCC silver conductors.
- Each signal path incorporates 8 solid-core 5N OCC silver conductors in multiple gauges: 18GA + 24GA + 26GA + 28GA + 29GA + 29GA + 32GA + 32GA.
- A 1.0-meter stereo pair uses a total of 4m × 12GA + 4m × 20GA Duelund tinned copper conductors, together with 4m × 8 solid-core 18GA to 32GA 5N OCC silver conductors.
- Multiple types and layers of shielding materials are incorporated to help reduce noise and RFI/EMI interference.
- A unique damping design combines various anti-vibration and damping materials to help suppress and isolate unwanted mechanical vibration.
- Standard length: 1.0m, with additional length options available.
RCA Plug Selection
The choice of RCA plug provides an additional opportunity to fine-tune the cable to suit individual listening preferences and system characteristics.
- Gold-plated RCA plugs tend to provide a slightly warmer presentation.
- Rhodium-plated RCA plugs tend to offer greater high-frequency clarity and extension.
- Pure Silver RCA plugs can provide a greater sense of air, openness, and fine detail.
Sonic Character
The Xtreme Silver Series RCA Interconnect combines 8 solid-core 18GA to 32GA 5N OCC silver conductors per signal path with 12GA and 20GA Duelund tinned copper conductors.
The design brings together key sonic qualities of both the Xtreme Series and True Silver Series, while presenting them in a more balanced and integrated manner rather than emphasizing the distinct characteristics of either series individually.
From the Xtreme Series, it retains the natural, smooth, and highly musical presentation associated with the classic Western Electric-inspired sonic character, complemented by a quiet background and well-balanced overall presentation.
From the True Silver Series, it introduces the sweetness, delicacy, speed, dynamics, and fine detail associated with high-purity silver conductors.
The result is a carefully balanced combination of classic Western Electric-inspired musicality and modern pure-silver transparency, speed, and refinement. This versatile sonic character makes the Xtreme Silver Series well suited to a broad range of high-end audio systems.
Conductor Cross-Sectional Area
The estimated conductor cross-sectional area per meter, per +/− channel, is:
- 5N OCC Silver: 1.48mm²
- Duelund Tinned Copper: 3.83mm²
Humble Comments
If you appreciate both the classic Western Electric-inspired sound and the clarity and refinement of pure silver, and find it difficult to choose between the Xtreme Series and True Silver Series, the Xtreme Silver Series offers an excellent balance of both sonic characteristics.

Selecting the Right Audiolund Series
For simplified product selection:
- Xtreme Series – For enthusiasts who prefer the classic vintage Duelund/Western Electric sonic character.
- True Silver Series – For listeners seeking the purity, speed, and transparency of modern 5N OCC Silver.
- Xtreme Silver Series – For those who enjoy the Duelund/Western Electric signature with additional silver-derived refinement and detail.
- Ultimate Silver Series – For listeners who favor silver performance while retaining elements of the classic Duelund character.
- Flagship Series – For those seeking an equal balance of both sonic signatures.
OPTION: Select Cable Sleeve Color:

1) Default: Red copper + Black Strip with Black Backgrounds

2) Optional: Red Copper + Red Stripe with Black Background
Cable Run-In
Most Audiolund cables use multi-core designs incorporating various conductor types, gauges, and combinations. As a result, they require an extended run-in period to reach their intended sonic performance.
The thick, solid-core OCC silver conductors typically require a longer run-in period than Duelund tinned copper conductors, which use multiple parallel strands of finer wire.
As a general guideline:
- Most Audiolund cables: approximately 100 to 200 hours
- Xtreme Silver Series: approximately 200 to 400 hours
Because the Xtreme Silver Series incorporates multiple solid-core OCC silver conductors together with Duelund tinned copper conductors, additional run-in time is recommended before making final critical listening evaluations.









As a music lover, I have been intensively involved with the HiFi topic for 33 years.
On this trip I tried out a lot of cables, some of which were excellent and extremely expensive, in order to optimize my system.
I discovered Audiolund by chance and tried them out: These Audiolund cables are the most balanced in my system so far, they can easily hold their own against all other products on the cable market that are many times more expensive (with dubious prices!).
The entire cabling of my HiFi system now consists almost exclusively of the Extreme Silver and Ultimate Silver Series and I am more than very happy with it.

The sound stage is more in depth, the music is more enveloping, and what about the bass wow!
An enveloping musical immersion, an exceptional musical presence!
