No wonder you're getting poor sound with cheap jumpers. Paper clips indeed!
You need to get the new Super Jumpers by Reptile Grease. $1,100. Each.
You get what you pay for. You'll love 'em.
I think that you’re missing the part where
- The OP said that there were no jumpers
- The OP ordered bi-wires
The paper clips would actually give the OP a listening experience before the new bi-wires arrive.
My recommendation is along the lines of what some would refer to as “Clear thunking”
