I have the same speakers and use 6' Zu Libtec cables with Ibis jumpers, the Libtecs hooked to the lower posts. I suggest trying some Analysis jumpers.
Bi-wire Silverline Prelude II: Is it worth it??
I have a pair of Silverline Prelude II speakers. They can be bi-wired. Need input from owners of the same model if it is worth the expense of another set of cables to bi-wire. I have Analysis Plus Oval 12 and would only invest in another pair of speaker cables if they will provide improvement in bass control and HF frenency smoothness. Thanks Jim
