Sashafan - you might be trying to fix with cables a problem that resides in your gear elsewhere. I couldn't think of anything worse than listening to Wilsons at a high sound level. The Sasha's have a suckout in the lower midrange, cone breakup at 4k and big peak in the upper midrange/treble. Check out the Stereophile review - they are extremely difficult to set up due to these on/off axis frequency aberrations and impedance dips that the amplifiers see.
