Are you mass less

I have no idea if cheaper interconnect ends will be "as good". However, I started using low-mass BFA style bananas after I bought and used a pair of Nordost speaker cables with their Z-Plug version of the BFA style low-mass banana plugs. I think the most important factors for the BFA style banana plugs would be material type and connection type. I've typically soldered mine onto the speaker cables. However, there are also screw on (but they have more mass) and some have crimp tabs on them. I've used the crimp-on type, but I've always soldered them and just clipped off the crimp tab. Not confident in my crimping technique.

I've been very satisfied with soldered-on low-mass BFA style banana plugs.

Low mass everything in cable design are the main ingredient in Darwin Cables. From the connectors to the actual wire itself, it's all minimalist in design and execution, which is why I love them.

All the best,

I use a 47 Labs OTA cable kit.

The only metal mass in the female RCA is the 26 gauge solid core copper wire used for for the interconnect itself.

I suspect that the non-metal RCA is made of Teflon, but not certain.

When soldering rueb...are you doing the ends of wire/connector?...you need medium iron?...i have some mundorf and you/NNoise got me thinking.

wow dekay these are interesting stuff indeed.

dig, I wind the end of the stranded speaker cable pretty tight and tin it first. Then stick it into the "wire end" of the BFA banana plug and apply a bit of solder. I'm guessing my iron is medium heat, but not sure. I finish with red/black shrink wrap to seal the connection and provide a visual queue for proper phasing.
