61. Ultimate Silver Series ~ Speaker Jumper (OCC Silver + Duelund Copper)

• Uses 17 solid-core 5N OCC silver conductors per positive and negative channel: 15GA + 15GA + 18GA + 2 × 7 conductors (24GA to 32GA), combined with 1 × 12GA + 1 × 20GA Duelund tinned copper conductors.
• For a 25cm, two-pair Speaker Jumper set, a total of 2m × 15GA + 1m × 18GA + 2m × 7 solid-core 24GA to 32GA 5N OCC silver conductors, combined with 1m × 12GA + 1m × 20GA Duelund tinned copper conductors, is used.
• Multiple types and layers of shielding materials help minimize noise and RFI/EMI interference.
• A proprietary damping design incorporates multiple anti-vibration and damping materials to improve mechanical isolation and suppress unwanted vibration.
• Standard lengths: 20cm / 25cm
• Configuration: 2 pairs / 4 pieces per set
• Termination options: Banana plugs or Y-spades

The Ultimate Silver Series is available in two configurations:

1. All OCC Silver Wires, or
2. Duelund Silver Foil, replacing the 2 × 15GA + 18GA 5N OCC silver conductors with 2 × Duelund Silver Foil V1, while retaining the remaining OCC silver and Duelund tinned copper conductors.

Based on critical listening, the Duelund Silver Foil version offers a subtly more prominent midrange, with slightly greater vocal focus and a pleasantly warmer presentation.

The All OCC Silver version, by comparison, tends to present a slightly wider and deeper soundstage, with a more organic character and marginally greater perceived detail.

These differences are subtle rather than dramatic. Both versions provide excellent midrange performance, soundstage presentation, and overall musical quality.

Both are classified within the same series, combining pure silver conductors, either OCC silver or Duelund Silver Foil, with Duelund tinned copper. Their overall sonic characteristics remain closely related, blending the qualities of pure silver with the classic Duelund/Western Electric-inspired character.

The choice therefore comes down primarily to personal preference:

• Choose Duelund Silver Foil for a slightly warmer and more prominent midrange.
• Choose All OCC Silver for a slightly wider and deeper soundstage with marginally greater perceived detail.

Xtreme Silver Series

The Xtreme Silver Series uses the Xtreme Duelund Series as its primary conductor foundation, complemented by OCC silver conductors to create a distinctive Duelund + Silver sonic balance.

Ultimate Silver Series

The Ultimate Silver Series uses the True Silver Series as its primary conductor foundation, complemented by Duelund conductors to create a distinctive Silver + Duelund sonic balance.

The Ultimate Silver Series combines key characteristics of both the Xtreme Series and True Silver Series. It delivers the comprehensive, natural and smooth presentation associated with the Xtreme Series, together with a quiet background and strong musicality.

At the same time, it retains the sweetness, delicacy, speed, power, dynamics, and resolution associated with the True Silver Series.

As a simple guide, each series is designed around a different sonic character:

1. If you prefer the classic vintage Duelund/Western Electric sound, consider the Xtreme Series.
2. If you prefer a modern 5N pure silver presentation, consider the True Silver Series.
3. If you prefer the Duelund/Western Electric character with added pure silver characteristics, consider the Xtreme Silver Series.
4. If you prefer the 5N pure silver character with added vintage Duelund/Western Electric qualities, consider the Ultimate Silver Series.
5. If you value the Duelund/Western Electric and modern pure silver characteristics equally, consider the Flagship Series.

Both the Ultimate Silver Series and Xtreme Silver Series are designed to combine the sonic characteristics of Duelund/Western Electric conductors with modern pure silver conductors.

While their individual presentations remain distinguishable, both retain recognizable qualities from Duelund/Western Electric and pure silver. As a result, either series can integrate exceptionally well with a wide range of high-end audio systems.

Recommendation

If you enjoy both Western Electric-inspired musicality and the qualities of pure silver, either the Xtreme Silver Series or Ultimate Silver Series is an excellent choice.

The Ultimate Silver Series places greater emphasis on modern pure silver characteristics. The addition of Duelund tinned copper introduces greater musicality while giving the presentation a relatively smoother, softer and more relaxed character.

For listeners seeking the strengths of modern pure silver without sacrificing the musical qualities associated with Duelund/Western Electric conductors, the Ultimate Silver Series is highly recommended.

Additional Listening Notes

The Xtreme Series has a strong Western Electric-inspired character, with a balanced, natural and neutral presentation.

The True Silver Series offers a sweet, delicate, powerful and fast dynamic presentation characteristic of modern silver conductors, together with a stronger tonal presence and a slightly warmer, richer, fuller-bodied texture.

From a personal listening perspective, the Duelund/Western Electric presentation remains a favorite for its relaxed, detailed and highly musical character, while the True Silver Series is particularly appealing for its full-bodied and organic presentation.

In simple terms:

• Xtreme Series: Classic, vintage Western Electric-inspired sound with excellent musicality.
• True Silver Series: Modern pure silver sound with a full-bodied, organic and dynamic presentation.

Neither approach is inherently better. Both offer excellent performance, and the preferred choice ultimately depends on the listener’s system, musical preferences and personal taste.

As a general system-matching consideration, listeners using tube amplification may find the Xtreme Series particularly complementary, while those using solid-state amplification may prefer the presentation of the Silver Series.

The outstanding quality of the Xtreme Series is its musicality, while one of the greatest strengths of the True Silver Series is its full-bodied, organic presentation.

This philosophy led to the development of the Xtreme Silver Series and Ultimate Silver Series, combining selected qualities of both conductor families into two complementary hybrid designs.
