If your system sounds somehow harsh, maybe you should start addressing the core of that problem.
If you have a good music source (analog or digital) and decent cables, I wouldn't spend money on new cables. I would try different inexpensive tweaks that will help "cleaning" and improving resolution, leading to a more real and warmer sound. I mean antivibration pods, ferrite cores, tube damping, etc.
Also consider AC treatment, a big source of noise and harshness. Of course, AC power filters or AC regeneration is not cheap, but maybe a dedicated AC line is cheaper. All of them will help a lot.
