Do powercords make a difference in sound?

classic troll.

pick up an old scott receiver from mapleshade and a nordost odin power cord and you are set to go...

I have 3 Transparent ref. powerlink's mm2, and short answer...yes. The source and pre-amp had HUGE improvements in dynamics. Improvements on the amp was VERY disappointing, it did remove some haze and improve the sound a little but not sure worth it. oh well.

By all accounts PCs are largely component specific. While I have tried my hand at them with various items in my stereo, they have yet to make a particularly meaningful improvement. If you pose a more specific question, people with the same electronics as you may have a PC brand/model suggestion.
