I went to solder the high frequency leads directly to the low frequency binding posts last night and found the wires are terminated with a female flat spade connector which slides onto the male spade tab that is clamped/nutted to each binding post. I'm not inclined to cut and solder the leads on.
So you found out they used the cheapest fastest crappiest connector and want to leave it that way, in order to spend more money on the best wire in order to have it connected to the crappiest sounding connector. Is that right?
Are you sure?
I have yet to see one of these things that couldn't be removed by pushing a nice sharp pick into the crimp and prying it open. With the wire out you solder it and then if you want to keep the crappy connector for the next guy tape it inside there somewhere.
Just realize you're looking at a situation that for absolute dead certain could be improved more with some Total Contact on the connectors than you could ever get from any jumper.
Once again I am amazed at how cheap parts are used in expensive components. Mods rule.
