Foster,
Yes, it can!
I have had to deal with some noise issues associated with power cord proximity to IC to the power amps. Also, tube noise was part of the mix.
It is under control currently. But I should probably redo all my wires to provide better isolation. I have found with this kind of thing benefits do not end once you do not hear an effect. There can still be subtle effects at play that are not obvious until addressed further.
