silver with tubes and copper with solid state ??

i am not one to generalize. however, a recent experience with a solid state amp has led to the hypothesis that copper cable may be a better match for solid state than silver cable, while some silver or silver-plated cable may be preferable to copper cable when using tube amplifiers.

the basis for this hypothesis is the possible emphasis in the treble from silver cable and solid state amps. thus, one peak + another peak=trouble.

what are your experiences in this regard ?
