The Cables

Unlike other vendors, Iconoclast doesn’t have an entry-level cable. The goal was to build the best cable within the limits of science, physics, and manufacturing.

The design and geometry of each cable remain consistent. The only difference is your choice of conductor, connectors, and length. All cables come with a test report showing measured values for capacitance, inductance, and resistance.

All terminations are soldered with WBT silver solder.

Iconoclast Silver-Plated TPC (SPTPC) Speaker Cables

Price: $2,800 / 10 ft pair

Design Insights

  • Speaker cable design goals primarily involves lower resistance. Using large gauge wires results in lower resistance but higher inductance and inconsistent current density.
  • A large number of individually insulated conductors will help but will increase capacitance.
  • With this braid configuration (conductors in the same orientation to the opposite polarity as one another) it’ll reduces inductance significantly with only a small increase in capacitance.

Specifications

  • Electricals
    • Capacitance: 45 pF/ft
    • Inductance: 0.08 uH/ft
    • Resistance: 1.2 ohms/1000 ft
  • Geometry
    • Each polarity leg has twenty-four, 24 AWG conductors.
    • Pairs of conductors are extruded into Teflon “bonded pairs”
    • The resulting 12 bonded pairs are braided (basket-weave)
    • The two legs are then laid back-to-back with a nylon braid and FEP outer sheath.

Price:

  • 4×1 – $1,950 per 5 foot pair
  • 4×4 – $2,250 per 5 foot pair

Design Insights

  • Inductance and capacitance are more important for lower voltage, line level cables.
  • Star quad geometries are great for rejecting noise at the cost of higher capacitance.
  • This modified star quad design offers superb common mode noise rejection without the high capacitance.
  • The Series II uses tiny conductor geometry star quads reduce inductance further, with a small increase in capacitance.

Iconoclast RCA UP-OCC RCA Interconnect Cable

Price:

  • 1×1 – $1,750 per 5 foot pair
  • 1×4 – $2,050 per 5 foot pair

Design Insights

  • The best dielectric is air. These air tubes have an outer FEP jacket and double bare copper braid shielding.
  • Instead of a single conductor, the 1×4 design uses four smaller conductors in a star quad. This produces lower inductance due to field cancellation between the four conductors.
