after market power cords for power conditioner or amps etc

What is the rest of your system?

What is your budget for PC?

I replaced the chords on my amps, preamp, & source with Nordost Red Dawns. It hurt but there was a noticeable improvement. I plug them into a Niagara 1200 for power conditioning. The Niagara definitely made the biggest difference for me.

thanks for the input on the brands of power cords.  What I am really interested in is whether to upgrade the power conditioner power cord instead of each component cable. It sounds like zyphryx is saying the most significant change in sound was a result in upgrading the power cord to Niagara.   I have all Mcintosh two 611 and one 302 amp and mx122 a/v processor.  

Get a USED cable that retailed for $3-500 for at least half, and use it for the wall to conditioner.

Do it again for a another, then experiment to see if you hear a difference in different spots.

Brand suggestion is contentious, I stay out of those conversations. As the precious poster mentioned, I have a full setup of those kinda pricey, cables.

Gottem all used, otherwise can't afford such extravagance.  The retail total is absurd.

ok thanks
