Screw on banana/spade connectors

Nope. Not going for it. "Last time". Remember?

Impossible. There is no such thing as high quality screw on spades. There is no such thing as a great deal on a cable with screw on spades. What there is, is something one tiny little step up from lamp cord. Have you priced lamp cord? You should. Its a great deal. Compared to screw on spades. 

Again, last time, its all about the sound. Not how it looks. How it sounds.

If you're concerned with signal loss with a connection, which you should be, then why would you want to add another connection? Of course there's gonna be all kinds of problems with anything that screws on. That's the kind of low end connection electricians use when all they care about is getting current from A to B without burning the house down. Its called a wire nut. Would you ask about using a wire nut? Of course not. Yet how is this any different? 

So you have bare wire. You can spend a small fortune on a quality spade connector and solder it on there with rosin and quality silver solder like a real audiophile, or you can tin the same wire without the spade and connect it directly which will be even better. Or you if you don't want to solder then you can just twist the wires and tighten down real good.

What you do not do is screw some dreck on just because you think its supposed to look a certain way. Its not about the look. Its about the sound.
