content: 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.

content: 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).

content: Copper bananas (these really are copper, with gold over silver plating):https://www.ebay.com/itm/4P-Viborg-VB401G-Pure-Red-Copper-5U-gold-plated-Banana-Connector-Terminal-Plug/253112114600?hash=item3aeea85da8:g:QggAAOSwxvBZnkXwGold over copper. These have to be soldered. Keep the wire close (in contact) with the connector and you should be OK. These are very low mass, and quite inexpensive.https://www.ebay.com/itm/New-Dyson-Audio-24k-Beryllium-Copper-Low-Mass-BFA-Z-plug-Bananas-8-pack/112250971825?epid=851403366&hash=item1a22ade6b1:g:dU0AAOSw-kdXzOrkYou can find some nice shielded twisted pair on eBay. Or, RG58. Solid core crimps better.It is easy to break the plastic around the jacks, so make your cable so that the plugs sit parallel.

content: QuoteYes, 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.
