- Employs multiple types and layers of shielding materials to help reduce noise and RFI/EMI interference.
- Features a unique damping design using multiple anti-vibration and damping materials to suppress and isolate unwanted vibration.
- Standard length: 20cm / 25cm

Sound Characteristics
The Xtreme Silver Series Speaker Jumper combines eight solid-core 5N OCC silver conductors, ranging from 18GA to 32GA per signal path, with 12GA and 20GA Duelund tinned copper conductors.
Designed to bring together the strengths of the Xtreme Series and True Silver Series, the Xtreme Silver Series offers a more integrated and balanced presentation rather than emphasizing the distinct character of either series individually.
It retains the natural, smooth, quiet, and highly musical character associated with the Xtreme Series and its Western Electric-inspired sound, while incorporating the sweetness, delicacy, speed, power, and dynamic expression of the True Silver Series.
The result is a carefully balanced combination of classic Western Electric-inspired tonal qualities and modern pure-silver characteristics, making the Xtreme Silver Series highly versatile and well suited to a wide range of high-end audio systems.
Conductor Cross-Sectional Area
Estimated cross-sectional area per +/− channel:
- Duelund Tinned Copper: 7.65mm²
- 5N OCC Silver: 1.48mm²
Recommendation
If you appreciate both the natural, musical character of Western Electric-inspired sound and the clarity, speed, delicacy, and dynamics of pure silver, and find it difficult to choose between the Xtreme Series and True Silver Series, the Xtreme Silver Series offers the best balance of both.

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.

Jumpers’ lined audiolund cables deliver exceptional sound quality, music becomes clearer with depth and detail that comes to the surface. The vocals are so present and the bass is powerful and well focused, the HFs are precise and detailed. Truly, Danny is a real jeweler of making cables that are great in sound and workmanship. The result is breathtaking, it’s as if I had changed my amplifier
Fantastic product. Highly recommended
