Can one use assymetric wire gauge for speaker cable construction?

Hello,

I am trying to build a DIY speaker cable, but while doing so I have one question that needs to be answered. I am using a cable which is essentialy made up of multuple individually insulated cables of smaller gauge.

So can I use more strands for the positive wire & lesser strands for negative wire, essentially an asymmetric gauge design. But length of both positive & negative wires will be same (and between left & right channel).

 

Can someone please help me answer this question?

 

Regards,

Saurabh

DIY itself is not a good idea. Let the guy screw around with his extension cords and figure that out for himself. Eventually. Maybe.

More resistance is not desirable in speaker cables. Use the heaviest gauge, don't bother with asymmetry.

There is one caveat pertaining to asymmetric cables and that is they DO NOT work well with amplifiers that adopt a balanced symmetrical differential design.

i.e. - where both speaker output terminals carry the same signal, but 180 degrees out of phase

This style of amplifier REQIES prefect symmetry between both +ve and -ve conductors - i.e. wire type, gauge, insulation type and cable geometry

There are several amps that use this approach and the list appears to be growing quite fast - but at this point in time they tend to be higher end products.

Here are a few

  • Accuphase E-303
  • Anthem - Some Models
  • Atma-Sphere - all models
  • Audio Research - Some Models
  • Ayre - all models
  • Balanced Audio Technology
  • BAT VK-255SE
  • Boulder 500AE
  • D’Agostino - Some Models
  • Musical Fidelity - High End Models
  • Pass Labs
  • PS Audio BHK Signature 300
  • Vitus
  • Yamaha some models
