What is the order of power cord priority?


I have never had seperates before. Now I'm moving to SET seperates. I presently have two Harmonix Studio Masters. One of my cdp and the other on my tube integrated. I cannot spring for the $$ for even used Harmonix. Where should these two babies go? Third recommendation for the one I will need to purchase?

I agree with Tobias and Warrenh, first on cdp and preamp.
Also a good pc needed for a power distributor or power conditioner, maybe the 3d in order.
Assumed the mains were sorted.
Have to agree with Dewald re mains but disagree re upgrading i/c's etc - if the mains is not sorted you are wasting money on i/c's, speaker cables.
However even with crap mains, power cords/conditioners will bring a far greater gain than fooling with signal cables.
