RCA Interconnect


For our IC3 CG interconnect cable we use the highly regarded, multiple award winning noise-cancelling Lessloss cables, consisting of 288 individually insulated strands with a total conductive cross sectional area of 3.5 mm² per polarity.
We asked Lessloss to develop for us the perfected version of their already outstanding achievement, resulting in a performance that betters even the IC2 / S2 cable by much.



This is achieved by a different weaving geometry, now all conductors being in one and the same layer with equal distance to the center, allowing a near perfect 90° overlapping angle of the individual coils for near perfect noise cancellation:

C-MARC™ is a new type of Litz wire. C-MARC’s™ noise reduction is based on the bucking coil method using two counter-polarized coils. Every strand’s clock-wise turn aligns with a corresponding counter-clockwise turn of exactly mirrored diameter and step. The two resulting counter-polarized coils are mutually superposed. A second-scale fractal replication of the already bucking coils is then repeated. Through electrical cancellation of the induced noise, C-MARC™ provides an enormous signal-to-noise ratio in today’s demanding environment.

  • KLEI™ Absolute Harmony Bullet Plug
  • Audio Consulting 10% silver solder
  • Proprietary ground return lead
  • Solid wood housing, shielded by a weave of copper- and nickel fibers, -100 dB 1 MHz to 30 GHz
  • Bybee Gold Slipstream Quantum Purifier in series
  • 16-cm electromechanical spiral resonator both in series and parallel


This interconnect comes fully burnt-in, pre-aging the cable equivalent to several years of usage in your system!

CG stands for “competitors’ gear” which means that this cable is perfectly suited for connecting non-Boenicke Audio electronics. Our own electronics incorporate tuning devices like the resonators and the Bybee filters, therefore they do not need to be introduced to the system by means of this interconnect cable.



“…Der Hallraum der Aufnahme erhält durch den Einsatz elektronischer Sounds einen Tiefensog, den ich mit der Kombination aus S3 und IC3 CG intensiver als je zuvor empfinde…

Falls es Ihrer Kette an Magie fehlen sollte – es könnte sein, dass die Boenicke-Kabel Ihnen den fehlenden Zauber bescheren…”

“…If your system lacks enchantment, the Boenicke cables may give you the missing magic…”

“…While my limited exposure to expensive interconnects is the only reason behind the absence of another award, I will say that Boenicke Audio’s IC3 CG emerged as the best of its kind I’ve yet heard…”
