Creek 5350 "U" bars

I bought this integrated used here on the gon, and have read a couple of reviews that state that the little "U" bars connecting the pre-amp to the power amp need to be upgraded to something better. Does anyone have any information on this, and what would I upgrade them to? It seems strange to me that this quality of amp would need upgrading right from the get-go. I would appreciate some info on this.
