Technical Notes:

Can cable make a difference in a system?

Yes, a high fidelity cable will reveal the details and nuances of the recording and sound reproduction. A poor cable will alter or
distort the signal from component to component and the full potential of the audio system is compromised.
The effect from a cable on a system may be very small to a large degree, but it's not always an easy thing to differentiate between
cables for most people. It is much easier to differentiate the differences between two speakers as compare to 2 cables. Through
experience, a trained ear, and careful A-B listening sessions, you can notice the difference a cable makes (for better or worst) on
a system. Furthermore, the audio system (CDP, preamp, amp, speakers) has to be revealing enough for you to hear the
difference.
If you truely cannot hear the difference when changing cables in your system, then maybe your system is not revealing enough
for you to notice the difference, and you should use the cable that you prefer based on value and performance.
A well designed high fidelity cable will provide improvement in the high and low frequencies, transparency, smoothness,
soundstage, and musicality. Be aware of certain cables that boost a certain frequency range (mids, upper bass or highs), which
at first may be striking but over time it will be fatiguing or flawed and not very enjoyable over the long run.

What is the best insulation material for high fidelity cables?

Most low end (mass consumer) speaker cables are made with Polyvinyl Chloride (PVC) insulation. These are cables that you
typically get at Circuit City, Best Buy, and Radio Shack (ie. Monster cables).
Polyvinyl Chloride (PVC) has a high dielectric constant and actually attacks the copper over time (copper poisoning) and this type
of insulation should be best avoided for a high fidelity audio system.
Polyethylene (PE) is a step up from PVC. PE has better dielectric properties. Using the same cable design, a PE insulated cable
will sound better than PVC. Many hi-end cables are made from PE or Foamed PE insulation and they can be priced from a few
hundred to thousands of $$$.
Polypropylene (PP) is slightly better than PE in dielectric property and should be better than PE. However, PP is a very stiff
material, so the cable made from PP insulation has very low flexibility. Only a very few companies make PP cables for audio
applications.
Teflon (FEP, PTFE, PFA) is most recognized as the best insulation in terms of dielectric properties and resulting in the best sound
for audio cables.
However, Teflon is very expensive as compare to PVC, PE, and PP. Teflon can cost like $20.00/lb vs $2.00/lb for PVC. That's why
you don't see Teflon cables on mass consumer audio cables and rarely see them in the $150-$300 price range for high fidelity
cables.
Zentara Cables use a proprietary Teflon insulation on our speaker and interconnect cables for the most musical and natural
sound.
