* HELIX Q & A

HELIX Q & A

Over the years I have often been asked a few questions repeatedly, which hopefully I have answered below.

Which Helix cable should I make first?
  • I normally recommend making the speaker cables first, because they are the easiest to fabricate and they provide the most noticeable improvement in sound quality
  • Next I would recommend the Interconnect cable, because it eliminates noise on the neutral side of the attached components, which improves clarity and imaging
  • Power cables should be the last to be built, because without the Interconnect or Speaker cables the full impact of the Helix geometry power cable cannot be completely observed

Power Cables:

What gauge wire should I use for the various components ?
  • I have found that for Amplifiers a 10 gauge Live conductor with dual 12 gauge neutral and ground conductors works the best
  • For source components I have found that 10 gauge provides no benefit, so I use a 12 gauge Live conductor with dual 12 gauge neutral wires and a 12 gauge ground wire conductors works the best
  • However, for some components, such as a TV, a 14 gauge neutral conductor with dual 14 gauge neutral wires and a 14 gauge ground wire works very well.

Do I have to solder the spades to the wires?
  • I have found that crimping + soldering provides the best results,
  • Crimping Only, works almost as well, so omitting the solder will not cause a significant impact to sound quality
  • Bare wires do not perform as well as spades and it is highly probable that the clamping device in the plug/connector to work loose over time.
  • Not only are spades an important safety consideration, they do actually improve performance

Interconnect cables:

Can the Helix Cable be used for connection between the Turntable and the phono stage?
  • Absolutely - the Helix spiral provides excellent shielding for the delicate audio signal from cartridges
  • I would recommend using 28 gauge wire for the signal and three 20 gauge conductors for the Helix coil


Can a Helix Interconnect Cable be used as a SPDIF (digital) interconnect?
  • Absolutely - they are excellent for digital transfers and the KLE Innovations RCA’s ensure they are completely compatible with 50, 75 and 100 ohm digital interfaces
  • Internal reflections, a common problem in other SPDIF cables are mitigated by using the KLE Innovations RCA plugs
  • Based on my own observations, the KLE Innovations Silver Harmony provides adequate capabilities to handle all digital transfers up to 24 bit 192kHz
  • If you require larger/faster transfer rates I would recommend upgrading the RCA to the Pure Harmony or Absolute Harmony model
  • You can also use cables shorter than 1.5 meters for digital transfers - I have used Helix cables as short as 45 cm without any noticeable degradation in signal transfers.
  • A minimum length of 1.5 meters is often cited as providing the best performance for other cable geometries.



All Cables:

Do I need to ad a wire “mesh” screen to interconnects? e.g. similar to COAX cables
  • No - the helix neutral & ground conductors act as a very effective screen

Do I have to use the components (plugs, wire etc..) listed on the site ?
  • Absolutely not, you are free to use whichever materials you feel are best suited to your budget.
  • However, all materials listed on the site are those I have found to provide exceptional sound quality.
  • Unfortunately I cannot provide an opinion as to the performance or materials you may wish to select, my apologies.

How does the Helix geometry compare to other “cable geometries”, such as the ribbon style geometry
  • The helix geometry is superior to other geometries in that they prevent noise form entering all connected components via the conductors
  • The Helix geometry can be used to build Speaker, Interconnect and Power Cables. Other geometries may not “scale” so well to power cables in particular
  • The helix windings serve as a very effective screen to deter noise pollution from external RFI/EMI sources entering your system

Can I use Helix cables on any audio/video equipment ?
  • To my knowledge helix cables offer significant improvements to sound quality on both Tube and Solid State equipment
  • Power cables tend to offer a more noticeable improvement on those components the have a less robust power supply
  • When used on large mono block amplifiers the improvements in sound quality tend to be more subtle in nature, but still noticeable.

They look very complicated to build - are they?
  • Perhaps the first cable you build will present some challenges during construction.
  • But once you get the hang of winding the helix coil with the aid of a rod and drill then subsequent sets of cables will be much easier to fabricate
  • I recommend winding a “test coil”, using a piece of household wire to start with.


Does the direction of the winding of the helix coil make any difference?
  • IT DOES - PLEASE READ : Inside The Helix Geometry.
  • It will not harm your components if the Helix Coil is wound in the other direction
  • it just sounds better when the helix coil is wound in the correct direction.
