+1 for Calvinandhobbes.
cable upgrades on my DAC and Power amps provided different forms of improvement.
my DAC needed filtering to remove harshness and clean up the sound. My amps needed a more open current flow. My power cables did not work well in my DAC and my DAC cable did not work in my power amps.
if I had to do one first think I would do the DAC cable because that ‘took away bad’ whereas the power cables added good, if that makes any sense.
But that’s in my system, with my electric, etc.
I don’t think I included cables in my profile so for reference:
I have a dedicated circuit for my system.
power cables for monoblocks and preamp are custom cables from Triode Labs/finale audio (maker of my amps)
power cables for DAC are Anticables level 3
