I did not read other posts, and this is the feedback from my own system. The cable differences in my system from most to least improvement is as follow: power cord for generator/conditioner; power cords for sources including streaming and disc transports; interconnects from DAC to pre, speaker cables, interconnects from pre to amps, and all others have small effects.
Do speaker cables really make a difference ?
Thinking about buying a different speaker cable. Do speaker cables really make a difference?
