Speaker Jumpers - Same Brand as Speaker Cables?

My speakers are best bi-wired. I currently have bi-wire speaker cables, but am considering buying very high-priced and probably better speaker cables that are single wire. The manufacturer of the new cables sells jumpers, but they are very expensive and not available used. Do I run an audible risk if I use jumpers from another manufacturer, or should I be "in for a penny, in for a pound" and bite the bullet? Thanks for the advice.
