Have audio cables really improved in last 20 years?

OP: By "really" improved do you mean improved "a lot" or "actually improved at all" (i.e., above and beyond marketing hype)?

@paulcreed Paul this is a very wide sweeping question which I can’t fully answer but one way of looking at it is to examine which cable manufacturers still sell the same cables from 10-20 years ago. If they are still being sold then they are in demand and then by simple deduction they must or have a good chance of sounding good.

Take Cardas for example the Clear Beyond range is still top of the heap so you could be confident in purchasing a used cable for a fraction of the cost.

Tara Labs’ top power cable was the Cobalt, it’s still in Tara’s current lineup but has two other power cables above it now with the top being almost three times the price.

So again by simple deduction the original Cobalt must be good because it’s still for sale, however they dropped the Onyx power cable.

So, I’m not being facetious but Tara Labs must have made some mighty strides in the last 10-20 years and seemingly Cardas has stood still or they cannot improve their Clear Beyond range.

One thing is for sure that prices will go up and wisely chosen cables have been a good investment for me over the last 20 years. Buy used when you can.

imho not substantially, but the highest offerings have certainly gotten significantly more expensive... cables in this industry have by far the greatest marketing content and least substantive content in all items sold... well except for things like tweaks like fuses and such...

@paulcreed - YES! cables have improved immensly over the past 20 years

There have been improvements in:

1. type of wire now used
   • Pure copper, OFC, UP-OCC copper and UP-OCC silver
   • The higher the Conductivity Rating the better the wire
2. type of insulation now used
   • PTFE, Foamed Teflon, Cotton/Silk etc...
   • they have a lower value of Dielectric Constant, which improved clarity and details
3. advanced cable geometries
   • this is how the conductors are situated within the cables
   • A good example of Geometry is the braided approach used by Kimber Kable
   • for examples of more modern geometries take a look at Zavfino, In-Akustik, Hijiri and the Helix DIY cables below
   • they have a lower noise floor due ot their geometry and insulations
4. Advanced connectors
   • pure copper is now used a lot more vs. the more manageable/machinable copper alloys (beryllium,teryllium) of of "yesterday" which have a lower level of conductivity than Pure Copper or UP-OCC copper
   • Low Mass RCA connectors have emerged and are far superior to those massive WBT RCA’s from the past

Compared to the more conventional wires that ARE still being sold as TOTL products, the newer cables are far superior and provide

• improved clarity and details
• an expansive and enveloping image
• more neutral sounding
• faster dynamic performance
• have the ability to make speakers "disappear"

With the right design approach and materials, today’s cables (some mentioned above) will get you closer to Audio Nirvana that anything from 20 years ago.

Unfortunately, just like anyting else in this hobby, YOU have to do your homework.

You can ask for opinions, but that will get you 100’s of recommendations, making the choice very difficult

But here are a couple of threads about some great sounding cables to be going on with and lots of comments from other members

• Zavfino
• Hijiri

You can of course, be like many other members and DIY your cables - in which case these threads may be of interest

• Helix DIY Cable Design
• Helix DIY - what other members think
• The Helix Cables are exceptional performers and can be built for a fraction of the cost, and will compete with some exceptional branded products

There is a lot of science behind the latest cables, but because many brands use unique terminology to advertise their products, and the advances can seem more like "snake oil". This can have a detrimental impact on possible customers, so they end up confused and will ignore the real breakthroughs in cable development

Hope that helps

It’s really hard to say “improved” as cables are so system and taste dependent.  It’s the true voodoo product in the industry.
