I have some Nextgen 0705 sets. if you really need WBT, I'll give it for a fair price. MSRP is 320USD for a set of 4: link. so you'll have nextgen for topline price
1 - about nextgen i have the doubt that are no robust insted of btass structure
2 - why you sell them ?

0705 is made of 99.996% pure oxygen free copper. then Gold plated
I bought them some years ago (2009), I've used some in some DIY projects. now some are remaining with no use.
Both actually work no better than the buck-50's from Radio shack. You are buying for bling and bragging rights. Pick the one that strokes your ego the most.
Gee, if they had not tired to make oxygen free copper, they could have gotten 6 9's out of it. Oxygen is used in copper to remove impurities. Totally irrelevant, but that is how it is made.
Let the flames begin.....

Yea, and that .000001 Ohm difference in the copper makes a big difference when they are nickle and gold plated, soldered with tin-lead-silver (and not in an inert environment) Of course, just touching a binding post is probably enough to cause the resistance to rise more than that last "9" of purity. I know, we need heat sinks and fans for our binding posts just like CPU's!
The problem here we are trying to help folks with is that there is a big difference between empirical physics and engineering. Let's let NIST worry about international standards and if the gram has actually evaporated enough to measure. I'll stick with my nickel over brass terminal blocks so I can afford better tweeters. We have a tremendous way to go before speakers catch up with he rest of the chain, so let's work on the parts that matter. I could provide a list if anyone were ambitious or looking for a thesis project.

I think WBT is from before the internet was invented
might explain the prices
at the time it was probably very expencive to construct this kind of special stuff, and market it
time have changed a lot since then
but some older companies have a hard time keeping up with the new and cheaper internet market
they are founded on a different 'strategy'

there is no substance or compound with 100% of conductivity!! (absolute 100?!... mmh nothing is absolute)
I haven't done listening test's of the binding posts, but I have for interconnect connections.
The WBT NextGen RCA connectors (Silver), with the Eichmann Bullet's, where better than all other's tested. There was a clarity in sound most other's couldn't match.
I don't know if this answer applies to your application.

I didn't say anywhere that coppers conductivity is 100%.
What I said was that if we take standard coppers conductivity [as a benchmark and] call it 100% oxygen free copper can ideally reach 101%.
Silver then would be probably around 105% or so and gold in between the two.
If you use the actual conductivity values copper reaches 58 siemens and oxygen-free copper can reach 58.68 siemens.
Nope, we are engineers. Be my guest. I am sure the manufactures will help you get published with several glossy adds on the facing pages. Pays their rent you know. I would like to see the system you intend to use for a reference. Let me know what the amp topology is, what it's output filter looks like, and what type of dominant pole compensation it uses. Try as you might, audio will just plain not violate the laws of physics.

These are the numbers for empirically pure metals. Metals alloy, as in everything outside the laboratory, is not as good.
As you can see, gold is no where near as good a conductor as copper or silver. When C.D. says 105%, he is speaking in relation to copper, the reference of copper being "1".

ahh, that's where the peaked sound comes from
btw, gold plated silver is said to be quite good
never had the pleasure, but have to do with tinned copper
