The real answer is very simple:
for ICs - use balanced XLR cables on your balanced components; if you don't have such components buy them (and avoid components that are not properly engineered next time)
for Speaker cables - you will never be able to predict which ones will sound best, so use a cable rental/return place and keep trying ones with different inductances, etc.
