I've used a pair of the 4" cables for some AC testing. The 4" set had significantly lower capacitance than most other set of cables I tested.
That cable has large brass connectors, which could deliver thermal offsets. I've never found copper double bananas.
To CalMachine's point, it has characteristics good for AC.
DH Audio has some decent copper/gold spades (they have a thin layer of nickel under the copper, but I don't think that is so bad).

Problem is on my Advantest I got only banana
I'm looking for the best compromise.
If you want low EMF with banana plugs, look at the link I posted above. He is in your neck of the woods too.
For high precision measurements I only recommend 4W+S PTFE cables with gold plated pure copper banana plugs.
However we also have these Pomona cables in our lab and despite they are PVC tagged - we do not encounter low thermal emf issues if we are measuring on the 10V range.
We also have never observed voltage dips - touching these cables with human hand - during measurements - on poor PVC cables you would see such phenomena.
After a 2 year period of use - one of the cables shows little cracks (fissure) where the cable jacket touches the banana ends.
Also a nickel (brass) alloy is not the best material of choice (thermal noise) - probably Pomona did this to keep cost acceptable.

Thanks Flinstone for taking the time to comment on those Pomona cables

Absolutely right. That's one of the best offer both in quality and price. And yes, not so far away.
ap is forum member too. I would go with this.
AP is certainly a recommended source as he bites you almost in your back as a matter of talking - have a look in 3458A section on FLEBAY (PTFE 3458A).
However pay attention to the shape of the banana plugs - avoid sharp tips - they will damage the binding posts of your metrology DMM.
Both companies - MC (Staubli) and Pomona (Danaher/Fluke) offer loose banana plugs with a rounded tip ... otherwise your binding posts will get worn and binding posts are expensive exercise to become replaced on an Advantest/ADCMT 6581 unit.

When I got my 6581 already one of the binding post was already not in a good shape, the plastic ring that guide the banana plug was cracked, and it crack more ....
I have 2 options, change with one of the back from the instrument that I don't use (I could use the guard binding post) or replace all of them but it is not just unscrew and replace, need to use an aluminium plate with spacers ....
I would like to buy the "Test Leads 60" DOUBLE BAN SHLD BALANCED LINE" from Pomona

I have a few of these cables and like them.
But PTFE insulated cables and hollow banana plugs are much better
- avoid sharp tips -
Yes, that's right. I've already got some of those, and run the very first time in that trap. Actually you just have to look carefully, how to plug them, to do it without issues. In an environment with different users, I wouldn't want to use them too.

I'm already in touch with him form calibration of instruments.
