Default oxygen free interconnects

Hi

I have 2 monoblocks and preamp which need decent interconnects, read some reviews and it seems I need oxygen free/teflon cables. There's a big variance in prices. Is this reflected in the quality of sound? , any real world experiences/advice welcome.

cheers
shugg

Only if you believe it is.

Build yourself a pair of interconnect with a couple of strands of CAT 5 cable and you will have as good if not better interconnects than those "high dollar" interconnects. They are made to separate you from your money mostly. Cheers.

Or to "interconnect" the manufacturer to your wallet.

I have found microphone cable to make excellent interconnects. I used Mogami (because it's available in the states), but I'm sure you can find something in the UK.

Shugg, you might borrow a pair of good interconnects, spend a few weeks listening, then replace with an el-cheapo variety. You probably will hear a difference. What value you place on any difference you hear is your point of decision.

Oxidized copper, copper oxide, is an insulator. More highly oxygenated copper probably is noisier than the more oxygen free variety on the theory that pockets of copper oxide create noise-inducing boundary and diode effects. Silver does not similarly suffer the fate of oxygen as silver oxide is a conductor.

A second, audible factor influencing the sound (ie, the electrical behaviour) of cables, in my opinion, are dielectric effects of the surrounding insulation. Dielectric effects are undesirable because they introduce into the wire spurious electrical signals and phase anomalies at a level dependent, generally speaking, on the dielectric constant of the insulating substance. Teflon is the generally preferred insulator because it has a lower DC and therefore lower inherent levels of dielectric absorption etc. Air is the best dielectric but contains .... oxygen.

The highly regarded Nordost cables use silver surrounded by a mostly air (oxygen-free?) dielectric.

Look for interconnects made in Nepal(or maybe Mexico City or LA)....much easier to make things oxygen-free when there's little oxygen hanging around to muck things up.

Actually, copper oxide is a semiconductor - read diode - and it's rectifying effect on the signal is what causes all the problems, noise as well as loss of detail. Silver doesn't oxidize at room temperature; the tarnish you are seeing is a silver-sulphur compound that is nearly as conductive as silver and has little if any effect on the signal. You should always try to use oxygen-free copper at the least on anything you are going to put a lot of work into building and OCC copper or silver would be even better.

You can always find high quality well-made interconnects on eBay for pennies on the dollar, German eBay in particular.
