Enhanced Gauge Mass and Commanding Top-End Refinement
 
For reference-tier loudspeakers where the crossover demands serious current delivery and precise signal tracking, standard or thin factory binding links will significantly compress your system's dynamic boundaries. The Siltech Classic Legend MkII 680L Jumpers offer a powerful technical step up over the 380L, bringing a substantially thicker G9 conductor profile and enhanced shielding matrix straight to your speaker terminal infrastructure.
 
If your primary loudspeaker cables are high-current, thick-gauge models, matching them with the expanded mass of the 680L Jumper set ensures that the amplifier's control over the high and low frequencies remains perfectly uncompromised and balanced from the floor to the binding posts.
 
Key Features & Technical Evolution
 
Substantially Thicker G9 Conductor Profile: The 680L Jumpers drastically increase the pure gold-infused silver mass compared to the 380L. This expanded cross-section significantly minimizes transmission impedance and attenuation, allowing your system’s micro-dynamics and complex upper-register transients to pass completely unhindered.
Upgraded Military-Grade Multi-Layer Shielding: The proximity of speaker binding posts to heavy internal driver magnets exposes them to high levels of localized induction noise. The 680L counters this with a beefed-up, multi-layered MkII carbon and metallic shielding package that aggressively neutralizes incoming EMI and RFI.
Ultra-Low PEEK & DuPont Teflon Dielectric: By wrapping the heavier cores in a sophisticated 3-layer insulation matrix of PEEK and DuPont Teflon, internal capacitance is kept remarkably low and exceptionally stable. This guarantees that your amplifier's timing and phase commands arrive at both the bass and treble networks simultaneously.
The Cable Company
Premium Direct Plating Connections: Supplied as a high-precision 4-piece set and available in Spade-to-Spade, Banana-to-Banana, or Spade-to-Banana variations. Featuring heavy-duty, custom-engineered terminations with a direct, ultra-thick layer of nickel-free gold plating to completely eliminate contact distortion.
 
Efforless Headroom. Absolute Sonic Continuity.
 
The distinct advantage of the Classic Legend MkII 680L Jumpers is their ability to bring an incredible sense of scale and effortless relaxation to the upper-midrange and treble performance. Harshness, sibilance, and high-frequency "etching" vanish, replaced by an airy, beautifully extended soundstage and highly focused holographic imaging. Low frequencies benefit from an expanded sense of physical texture and punch, unifying your speaker's separate drivers into one singular, coherent acoustic voice.
