This makes no sense, but yet....

I've got two pairs of Nordost Blue Heaven rca interconnects, both one-meter. One pair has the current sprung loaded jacks. The other has the older fixed jacks (no spring loading). I had the sprung cables between my CDP and amp and they were unbearibly bright - headache inducing. Switching cables around I put the non-sprung cables in and for some reason they sound a little smoother in the treble. Is it possible for two of the same cable to sound different? Is it possible that the plugs could make a dramatic difference? Or am I imagining things?
