1-phono cables (from cartridge to phono pre) are most significant, as they deal with a tiny signal (.2mv - .5mv). not debatable.
2-after that the interconnect from your preamp to your amp is critical because that synergy is paramount to the whole signal path.
3-all the rest are situational and not consistent. every A/C power grid is different, interconnect from source to pre can be significant, speaker cables can be critical depending on the amps and speaker synergy. you cannot generalize. no absolutes.
