I need advice for power cords


In my system there are 4 components that power cords are interchangeable.  They are PrimaLuna EVO 100 Tube Preamplifier, PrimaLuna EVO 100 Tube DAC, Manley Chinook phonostage and Dayton Audio sa1000 subwoofer amplifier.   Should they all be upgraded, if not all which one to change to give me the most improvements.  I can't go crazy on cost, 1k to spend.   I've followed along with many threads on this subject. Always looking to make improvements to sound quality.   Many of you have much more experience with cables than I do so what do you recommend and I can do the research.  On a side note my McIntosh MC75's are vintage so old thin manufacturer cables and probably shouldn't change them. 

Thanks

Also...your best bet is to spend your money on a dedicated circuit for your audio gear - that will get noisy things like fluoresecent lights and vacuum cleaners and hairdryers off your "audio only" circuits. Also consider a power conditioner that will kill any line noise and break ground loops. I run PanaMax.


Any high quality Green Dot Hospital grade cord will do a very good job. The Pangea's are also a great bang for the buck. With power cords you start running into the law of diminishing returns very quickly...

My 30 buck Jelly Fish Green Dot is way better then the $200 Patrick Cullen AC cable it replaced....

Also what is everything plugged into. Upgrading Hubble outlets to Hospital grade or better is also a huge help.

You can always go Battery power/DC if you really want to spend money....
A shout-out to roberjerman.  You have a very limited knowledge of high-fidelity components,and cables.Remember,your system is only as good as it's weakest link.If you say power cords are just like expensive jewlery,then I guess we know where your weakest link is!
After doing a comprehensive re-capping job, I just upgraded the power cable of my McIntosh MC240 by purchasing a Transparent Hardwired 2-prong ($75.00), clipping off the inlet plug, stripping, tinning (silver solder) removing the strain relief, desoldering the original cable, replacing the strain relief with an appropriate size rubber grommet, and attaching the new cable.  To prevent strain on the connection, I fixed a nylon wire tie tightly just behind the grommet.  Voila!  Way better than the old stock cable.  I also put in an on/off switch.
